12604 ms_inputquery fails to parse a peak list if it contains no colons

Version 2.5.2 - released with Mascot Server 2.5.1 and Mascot Insight 2.5.2

11333 The default value returned by ms_mascotoptions::getPercolatorMinQueries is 100 and this is too low for when there are 15 features. Increased the value to 750.
11806 Make getProteinRatio() return negative standard deviation, standard error and p-values when protein ratio type is weighted, and add a new interface to ms_protein_quant_ratio for querying the reason why the values are unavailable.
11825 Performance improvements for ms_inputquery.
11856 The function getNumDiscoveredErrTolMods filters peptides based on Ions score below a significance threshold. This was also being applied to the Error Tolerant peptides as well and so erroneously filtered out some error tolerant peptides and their modifications.
11858 The Mascot Server Windows installer should now always set ForkForUnixApache to 0. If the IFLG_UPDATEAPACHEFORKOPT flag is set when calling updateForInstaller then the value passed in wst is ignored and setForkForUnixApache is always called with 'false'. This change is for Windows only.
11862 Support filtering of peptides using decimal mass values as doubles rather than strings. See ms_mascotresults::findPeptides.
11863 Use correct Xerces encoding transcoder when loading and saving xml files. Supports UTF-8 correctly now so that some latin characters are parsed correctly.
11883 Add support to ms_ms2quantitation::normaliseIntensities to allow for normalisation to selected peptides or proteins when using summed intensities.
11884 ms_ms2quantitation::getCombinedReportRatioNames now returns unique ratio names in file order rather than alphabetical order.
11885 Warning message : Attempting to call function matrix_science::ms_peptidesummary::getPeptide before createSummary() has completed with some files where _ignoreiosscorebelow is non-zero and it is an error tolerant search.
11888 Support for Visual Studio 2013, Update 3.
11892 Specificity visibility class was not allowing for multiple sites of the same name that differ by position.
11899 ms_umod_modification::findSpecGroup sorts modification sites incorrectly. For example, it does not find the correct spec group for Phospho (ST) if the input string is "Phospho (ST)" and the T specificity preceeds S in in the list of specificities. This is because the method doesn't sort the sites, so its internal string ends up as "Phospho (TS)", which is of course different from "Phospho (ST)".
11907 ms_peptidesummary::getQuantitationComponentForPeptide, should exclude a peptide if it matches more than one component. Added code to identify ambiguous components.
11937 Implementation of willCreateCache function that doesn't require a ms_mascotresfile object and checks both cache files.
11959 Performance improvements for ms_mascotresfile::getRepeatSearchString.
11960 Open cache files for writing as soon as possible to reduce potential problems with multiple processes trying to create at the same time

Version 2.5.1 - Released with Mascot Server 2.5

11686 Added support for global and per-group modification visibility for matrix_science::ms_umod_configfile
11705 Improved behaviour for chimeric spectra. New flag: matrix_science::ms_peptidesummary::MSPEPSUM_REMOVE_CHIMERIC_DUPES
11708 ms_peptide::getAnyMatch was broken and always returned true in version 2.4.4 and version 2.5.0
11718 Added new functions: getNumDistinctPeptideRepeats and getDistinctPeptide
11797 ms_datfile::updateForInstaller shouldn't update parse rules if Database Manager is being used.

10290 Added support for HTTP Communication to a Mascot Server
11234 Move quantitation support from the perl cgi scripts to Mascot Parser. See Peptide and protein quantitation
11235 Added a new function: ms_mascotresults::getProteinEmPAI
11358 When combining results files, need to check that quantitation methods match rather than just comparing names. Added a new function isMethodCompatible
11392 Need to be able to return std::string & parameters in Java. SWIG supports returning references to native types in Java by passing a single element array of, for example an int. However, it doesn't support this for std::string. Where a parameter is a std::string & it is now necessary to supply a StringBuffer object which will be modified by Parser. Note that const std::string & parameters are unaffected, and still expect a Java String
11399 Simplify the requirements for specifying the location of the unimod and quantitation schema files when using ms_mascotresfile. See Specifying xml schema file locations
11409 Temporary cdb file created even when MSPEPSUM_DISCARD_RELOADABLE not specified. Minor performance issue, but no other side effects.
11411 Save qmatch and qploghole in the cdb file to improve performance.
11415 ms_mascotresfile now inherits from the ms_errors class. See ms_mascotresfile now inherits from ms_errors
11422 Under Windows, file sizes stored in cdb files are limited to 32 bits. Larger files had 'wrapped around' values and cdb files will be rebuilt automatically for these files.
11425 New function ms_mascotresults::getIonsScore to return an ions score more rapidly than calling ms_mascotresults::getPeptide and then ms_peptide::getIonsScore
11438 The functions ms_mascotresfile::getObservedCharge and ms_mascotresfile::getObservedMrValue need an optional parameter for specifying the summary or decoy summary section
11513 Save the values returned by ms_protein::getCoverage in the cache

11266 New function: ms_mascotresfile::getNumEtSeqsSearched().
11190 The function getProteinTaxonomyIDs() now also returns taxonomy IDs for PMF results where they are available for Mascot 2.4.1 and later. In version 2.4.0, it only returned values from the proteins section (for ms-ms searches).
11269 Incorrect return value for getObservedCharge() when the charge state is greater than 8+.
11275 Additional return values for getThresholdForFDRAboveIdentity() and getThresholdForFDRAboveHomology()
11305 Get error: "Requested query 1, hit -64 in function ms_proteinsummary::getPeptide" with some PMF mixture results when creating a ms_proteinsummary

10943 Cron emulator improvements including new ms_cronoptions functions: getLoggingLevel(), setLoggingLevel(), getLogFileName() , setLogFileName() , deleteCronJob() and setCronJob() and new ms_cronjob functions: isEnabled() and setEnabled()
10979 Add support for RAWFILE and LOCUS to matrix_science::ms_inputquery
10991 matrix_science::ms_mascotresfile::versionGreaterOrEqual returns incorrect value.
10995 Internal change to allowed values for identity threshold.
11002 Change minPepLenInPepSummary functionality. Don't show proteins in which the only significant peptides have length < MinPepLenInPepSummary.
11018 matrix_science::ms_mascotresults::getThresholdForFDRAboveIdentity and matrix_science::ms_mascotresults::getThresholdForFDRAboveHomology can fail to get the best values.
11042 matrix_science::ms_mascotresfile doesn't fail safely if a cache file cannot be created due to incorrect permissions. Issue was introduced when Bug 10745 was fixed in version 2.4.0.
11041 On 64 bit Linux only, the function matrix_science::int ms_mascotresults::getQmatch() can return a 'wrapped' negative number in the extremely rare case of the qmatch_x= value being > INT_MAX. In such cases, it now returns INT_MAX on all platforms.
11094 Using matrix_science::ms_peptidesummary::MSPEPSUM_NO_PROTEIN_GROUPING can cause a crash when creating a ms_peptidesummary object.

Version 2.4.0, 9th August 2011. Released with Mascot Distiller 2.4

10536 IgnoreIonsScoreBelow is converted to a score and rounded to an integer internally. First fixed as bug #567 in version 2.3, but this minor issue was re-introduced in version 2.3.1
10610 "Possible duplicate accession string" errors caused by two accessions that only differ in upper/lower case.

10626 Font size in chm (help) file is too large.
10627 On Windows, NTFS, cache files get re-created when going to/from daylight savings. Cache directory names also change.
10628 New function: matrix_science::ms_mascotresfile::resetKeepAlive and added a %f tag for displaying the filename, which is useful with Combining multiple .dat files
10629 Small memory leak in protein family grouping.
10630 New function: matrix_science::ms_connection_settings::setUserAgent() and matrix_science::ms_connection_settings::getUserAgent()
10631 Rare crash when using results cache with family summary and minPepLenInSearch < minPepLenInPepSummary.

Use only the filename part of result files when constructing the cache filename for a multi-file peptide summary.

10745 Creating an ms_mascotresfile object with a 'junk' file when specifying RESFILE_USE_CACHE creates a (tiny) cache file. The second time the ms_mascotresfile object is created with the same parameters, it reads the tiny cache file but fails to set the INVALID_RESFILE error.
10749 matrix_science::ms_mascotresfile::getNumQueries() incorrectly returned -1 for the last file in a multi-file result set.
10780 Change definition of matrix_science::ms_mascotresults::isPeptideUnique to be unique per family member rather than per family.
10804 Change matrix_science::ms_mascotresults::getPeptideThreshold() to allow return of either homology or identity threshold as double.

Version 2.3.3, 11th October 2010. Released with Mascot 2.3.02

461 matrix_science::ms_umod_configfile::getElementByName() hangs if called with null argument. Now just returns NULL.

630 Accession strings with spaces in are truncated when loading proteins from cache.
632 Added new function matrix_science::ms_peptidesummary::getFlags2()
633 MinPepLenInPepSummary not used for family gouping. Also added function matrix_science::ms_peptide::getPeptideLength.
634 matrix_science::ms_datfile error message says that 'mascot.dat. file does not exist even when opening file with different name, for example 'not.mascot.dat'. Change message to output the name of the file.
635 Added support for Combining multiple .dat files
638 matrix_science::ms_mascotresfile::getRepeatSearchString does not include scans, rawscans, rtinseconds and index
639 Added matrix_science::ms_mascotresfile::enumerateQuerySectionKeys
641 Unigene reports too slow. A cache file is now created and used automatically. See matrix_science::ms_unigene
644 Added tags to pass through session_id and task_id in matrix_science::ms_mascotoptions::getExecAfterSearch
645 Can't load family report for an ET search with ignoreIonsScoreBelow >0 and < 1
647 Add Support for Python under Linux. See Python toolkit installation
649 Performance improvements for matrix_science::ms_mascotresults::getProteinDescription and matrix_science::ms_mascotresults::getProteinMass
653 Very slow to create cache files when > 100k potential proteins in the results file.
654 Concurrency issue on Windows when using matrix_science::ms_session
655 matrix_science::ms_fragment::getLabel returns an string with a truncated rather than a rounded neutral loss. For MetOx, this reports -63 rather than -64.
656 Concurrency issue: if two processes try to create a directory using matrix_science::ms_fileutilities::createDirectory at the same time, one process may fail.

Version 2.3.2, 11th May 2010. Released with Mascot 2.3.01

624 Family grouping no longer requires that the top scoring protein for a group appears as a lead protein. There are cases where more compact grouping can be obtained by making the highest scoring protein a subset/intersection.
626 In rare cases, a protein could be marked as a subset when it should have been another family member. This is because the algorithm defined a protein as a subset when all of the peptides were found in any other protein, rather than any other family member protein.
627 Change to matrix_science::ms_aahelper::ms_aahelper constructor when creating from a matrix_science::ms_mascotresfile. Added an additional optional parameter to pass a quantitation schema that will be used before calling matrix_science::ms_mascotresfile::getQuantitation
628 Functions matrix_science::ms_protein::getNumDisplayPeptides and matrix_science::ms_protein::getNumDistinctPeptides return incorrect values for an error tolerant search when the flag for aboveThreshold is set to true. Error tolerant matches are now ignored in this case.

Version 2.3.1, 29th March 2010. Released with Mascot 2.3

See Upgrading to Mascot Parser 2.3.x from 2.2.x For a summary of changes required to scripts using Mascot Parser 2.2,

17 Would like to collapse peptides that only differ with Isoleucine <-> Leucine. For the new protein grouping, peptides with the same same score and same query are considered to be the same, so, for example, Q <-> K will also collapse if the tolerances are wide enough.
117 matrix_science::ms_mascotresults::getNextSubsetProtein is now significantly faster.
511 Increase maximum number of enzyme cutters from 5 to 20 and improve error message and documentation.
523 Mascot security doesn't work when specifying user_type=computer_name on Apache. This was because the session file names are case sensitive under unix.
531 Allowed p value for significance threshold has been changed from 0 < p < 0.1 to 1E-18 < p < 1.
569 Change homology threshold reporting. Can now report a homology threshold value where the qmatch value is less than 100 and the version is Mascot 2.3 or later.
575 Session timeout fails to give an error if the session file has been deleted and guest is enabled.
582 Support 64 bit Java for Windows.
583 Better support for AMD processors.
584 Added a flag to matrix_science::ms_umod_configfile::save_buffer() for whether to validate.
585 Added matrix_science::ms_tinycdb for giving access to tinycdb files.
586 Cache the ms_peptidesummary results. See Caching Mascot Results
587 matrix_science::ms_mascotresults::isNA() should look in peptide matches and not protein matches. It used to return incorrect results in cases where there were no significant protein matches.
588 Add a function to return a 'histogram' for all ions scores. Added: matrix_science::ms_mascotresults::getIonsScoreHistogram()
589 matrix_science::ms_aahelper::calcFragmentsEx() used to not take fixed modifications into account for searches where a quantitation method was specified.
590 Added functions: Added additional parameter to:
593 Add a function: matrix_science::ms_protein::getNumUniquePeptides()
594 Add a function: matrix_science::ms_umod_modification::getRecordID()
595 Add functions to find accessions, descriptions, masses, sequences:
598 Add Using Percolator scores
600 Add function to retrieve flags and other parameters required for creating an ms_peptidesummary or ms_proteinsummary.
601 Quantitation: Support Multiplex with multiple ions series (e.g. for IPTL)
Deprecated functions: New funtions: Updated schema from 2.0 to 2.1
606 matrix_science::ms_protein::isShowSubsets() does not read the value from mascot.dat because it is looking for ShowSubsets rather than ShowSubSets
607 Call to delete should be delete [] in ms_mascotresfile destructor. Will show up in valgrind as
          Mismatched free() / delete / delete []
            at 0x4C20A6E: operator delete(void*) (vg_replace_malloc.c:346)
            by 0x5B89ACB: matrix_science::ms_mascotresfile::~ms_mascotresfile() 
613 The only way to be able to get an ms_peptide object is to have an ms_mascotresults object which can be slow, so add a new flag to create an ms_peptidesummary object with no proteins. New flag added: matrix_science::ms_peptidesummary::MSPEPSUM_NO_PROTEIN_GROUPING
615 Support for EMBL EST Taxonomy and Unigene. New enumeration: matrix_science::TAX_SPECIES_ACC2TAXID

Version 2.3, 17th June 2009. Used with Mascot Distiller 2.3

198 Added matrix_science::ms_protein::getPepNumber() function, for when you're working bottom to top

465 Additional function for PMF iteration: matrix_science::ms_protein::getMasses
471 Added the function matrix_science::ms_peptidesummary::getQueryList(QL_FLAG flag) for an easier repeat search. Requires Mascot 2.3
474 In security, add parameter to restrict spoofing. Additional security task: matrix_science::ms_security_tasks::SECTASK_SPOOFNAMEDGROUPSONLY and function matrix_science::ms_session::getSpoofableUsers() that is used in Mascot 2.3 ms-status.exe for the Show=MS_USERS command.
497 matrix_science::ms_umod_element::setMonoMass and setAvgMass now check input parameters correctly
514 Added a new matrix_science::ms_aahelper::ms_aahelper constructor to create an object based on the masses and modifications in a results file. Makes it easier to produce the tables found, for example in the peptide view table.
530 Initial implementation of new protein grouping for Mascot 2.3.
Warning: This code is experimental and there may be further changes before Mascot 2.3 is released
Additional flag: matrix_science::ms_peptidesummary::MSRES_CLUSTER_PROTEINS and additional function: matrix_science::ms_peptidesummary::getNextFamilyProtein
Added matrix_science::ms_mascotresults::getTreeClusterNodes which is used to provide values for producing the dendrograms in the Mascot 2.3 reports. Note that new license C Clustering library needs to be included in applications that use Mascot Parser
536 Added a function: matrix_science::ms_peptidesummary::getAllProteinsWithThisPepMatch

444 If modification is missing from ms_modvector, ms_aahelper crashes and burns
370 Download of unimod.xml (0.5Mb) will be too slow over the internet. Parser now downloads the compressed unimod.xml, using the matrix_science::ms_zip class
442 Curl support has never worked on 64 bit AIX and possibly other platforms
441 Unigene support has never worked properly on 64 bit AIX release, (and possibly SGI/Sun/Tru64). The 64 bit Linux versions were not affected by this issue
440 Add a new option to mascot.dat - access through matrix_science::ms_mascotoptions::getMaxPepNumVarMods

343 Taxonomy strings can now contains commas.
391 Add method to ms_umod_modification to generate ms_modification objects.
393 Threshold cut-offs have changed. Old behaviour was to suppress the homology threshold if there were less than 1000 sequences in the search. New behaviour is to supress the threshold if qmatch is less than 100. There is also now a minimum for identity threshold of 13.
409 Verify enzyme used to return false if Restrict was empty
420 matrix_science::ms_mascotresults::getIonsScoreCorrected was incorrect if ITOL units were mmu rather than Da
421 Added matrix_science::ms_mascotoptions::getMudpitSwitch() and matrix_science::ms_mascotoptions::getSelectSwitch()

384 mascot.dat Options functions missing: SortUnassigned etc.
358 getTagStart, getTagEnd, getTagSeries stuck in infinite loop
313 Unigene file parsing not quite right. File format change in unigene files now processed properly
402 add validation precedures to fragrules and enzymes
395 Keep alives need to be flushed. On Linux, the keep alive html comments are kept in a buffer and not flushed. This means, assuming that the standard text and default time of 5 seconds is used, that it takes 20 minutes for something to appear.
386 Support for mulitple neutral losses. The function matrix_science::ms_searchparams::getVarModsNeutralLosses which returns an array of neutral losses has been added.
matrix_science::ms_searchparams::getVarModsPepNeutralLoss and matrix_science::ms_searchparams::getVarModsReqPepNeutralLoss have also been added.
387 The functions: matrix_science::ms_searchparams::getFixedModsName matrix_science::ms_searchparams::getFixedModsDelta matrix_science::ms_searchparams::getFixedModsNeutralLoss matrix_science::ms_searchparams::getFixedModsResidues have been added.

373 getSeriesName returns empty string for ion series 19,20
376 setDelta() for unimod modification disables mod delta
326 If an old ICAT search is repeated with Mascot 2.2 or later, then the ICAT=ON should be translated to QUANTITATION=ICAT. The name 'ICAT' is retrieved from the options section of mascot.dat using getICATQuantitationMethod()
327 If the require bold red flag is set, then the wrong protein number used to appear in the yellow popup. The protein accession string was correct.
328 Further changes to quantitation.xml design. [Remove from 2.2 changes list]
330 Support MODS and INSTRUMENT at the query level. See getINSTRUMENT(), getRULES() and getIT_MODS(). Needed for instruments that, for example, can switch between ETD and CID.
329 Support more than 9 variable mods. See Increase in the number of variable modifications for details on the impact of this to existing clients using Mascot Parser.
333 Add 3 new search parameters: getQUANTITATION() , getPEP_ISOTOPE_ERROR() and getDECOY()
248 Support for new PMF iterations introduced in Mascot 2.2
See: matrix_science::ms_mascotresfile::isPmfQueryUsed()
297 A Java or Perl application calling matrix_science::ms_aahelper::calcFragments can now access the fragments array.

Version 2.1.03, 9th March 2006

The following items were fixed in this release which was shipped with Mascot 2.1.04

300 Support high charge state fragments in aa_helper. Mascot only matches singly and doubly charged fragments, and there are no plans to change this. However, if someone wants to label peaks with higher charge states in Mascot Distiller or any other product that uses Mascot Parser, they can now do this.
301 aa_helper used to give a negative peptide mz value for negative charge.
302 calcPeptideMz() now gives correct mz values for higher charges.
307 A dual core Xeon system with HT disabled in the bios was not detected correctly. The work-around was to enable HT in the bios.
310 Process Affinity was not working on some 2.6 kernels (Linux). This has been fixed by using the PLPA library from Open-MPI.

Version 2.1.02, 18th October 2005

The following items were fixed in this release which was shipped with Mascot 2.1.02

263 If a search was run using 'MONOISOTOPIC' rather than 'Monoisotopic', then a repeat search using would submit the second search using average masses because it doesn't recognise MONOISOTOPIC. This has been fixed in this parser release.
270 The Tru64 release of parser 1.x sometimes gives a different sort order for the concise protein summary due to a bug in the Tru64 compiler. This problem has been fixed in this release by using a patched Tru64 compiler.
276 Advanced topic! MSRES_DUPE_REMOVE_A will always be set which causes incorrect filtering when modifying these advanced flags. This does not affect any standard reports.
280 getNextSubsetProtein() now always returns false unless MSRES_SHOW_SUBSETS is set. This makes coding for the client a little easier and more transparent.
281 In cases where the highest scoring protein has no bold red peptides, selecting REQUIRE_BOLD_RED used to return no hits. Obviously, it is very rare for the highest scoring protein to not have any rank 1 peptide hits.
282 Add SECTASK_BIOTOOLSBATCH in preparation for next Bruker Biotools release. Added this task to the PowerUsers group.
283 Some customers still have systems with the electron mass being incorrect from the Mascot 1.9 installation. 'Fudge' the code by returning the correct value (0.000549) if the value in the file is 0.00549.
If, so some bizarre reason, you really want the electron mass to be 0.00549, then specify it as 0.005490 in the masses file.
285 The matrix_science::ms_processors class now supports dual core AMD Opteron and reports that process affinity is available on Linux 2.6 kernels. Additional functions are now available to determine the name of the processor manufacturer and a description of the hyperthreading/multi-core/SMT functionality on the processor.
286 matrix_science::ms_protein::getFrame used to return -1 for protein database if the search was PMF. It now returns 0 as specified in the documentation.
287 and 290 Using the require bold red flag, it was possible to get occasional matches to proteins without any bold red peptides.

Version 2.1.01, 24th June 2005

The following items were fixed in this release which was shipped with Mascot 2.1.01

261 Java version of ms_aahelper fails. C++ and Perl worked OK.
262 Passing a directory name rather than a file name caused a crash.
266 ms_searchparams::getUSERID returns -1 for old searches - meaning that it is impossible to see old searches unless the view all searches token is set.
267 In rare circumstances, a single peptide match generates multiple protein hits. Only happens at the random matching level and if minPepLenInPepSummary is non-zero.
267 getErrTolModMasterNeutralLoss() returned an incorrect value.
272 Java Parser on Linux fails to run.
273 Performance improvement for results files with matches to a large number of ambiguous residues

Version 2.1.0, 30th April 2005

The following items were fixed in this release which was shipped with Mascot 2.1

2 Read and parse the Mascot configuration files. See Mascot configuration files module
122 Ambiguous residues coped with transparently. matrix_science::ms_peptide::getPeptideStr now takes an optional argument to specify whether ambiguous residues are reported with the substituted value
126 Documentation - ms_searchparams class reference had multiple references to MASS=
142 ms_protein::getFrame() is now a const function
143 Documentation - now specifies that oneInXProb has lower limit of 10
144 Documentation - now specifies that 0 is returned for auto in matrix_science::ms_searchparams::getREPORT()
145 Documentation - matrix_science::ms_peptide::getIonsIntensity() is now clearer
146 Documentation - matrix_science::ms_peptide::getNumIonsMatched() is now clearer
151 Provide functions to calculate peptide and fragment masses. See Mascot utilities and tools module
162 Example perl script for protein summary and peptide summary have incorrect tag calls.
164 C++ test harness: peptide_list.cpp only builds on Windows.
173 Performing a search in the Windows msparser help no longer gives the same 'Title' for all pages.
175 Documentation - Ions series are now correct in matrix_science::ms_searchparams::getRULES()
183 Peptides with and without ambigious residues are now split into two entries. When decides whether to check if one protein is a sub-set of another it now compares the substituted peptide strings instead of original.
186 Mascot User authentication and login. See Mascot security and authentication module
187 Re-organise the help into separate modules, and provide example code in the examples directory as well as the online help.
199 Huge results files loaded and parsed using less memory.
200 AutoSelectCharge is a new parameter in the options section of mascot.dat See: matrix_science::ms_mascotoptions::getAutoSelectCharge()
206 Before loading whole results file, check it really is a Mascot result file.
218 Support for negative charge state.
221 In the help, remove the class and class hierachy menu in the tree. These are now grouped together under the separate modules.

Version 1.2.2, 19th January 2004

The following items were fixed in this release which was shipped with Mascot 2.0:

134 Support non-threaded build of Perl on Linux. Perl supplied with RedHat Linux is normally built with threads support. The default build of Perl (and therefore the one supplied with most other Linux distributions) has thread support disabled. See Installation on Linux platforms for details of which version of is required for your system
135 If a query contains a tag or an etag, then the homology threshold is now suppressed.
137 New protein scoring for MudPIT type searches. See matrix_science::ms_mascotresults::MSRES_MUDPIT_PROTEIN_SCORE
139 Version string format in changed from, for example:
$VERSION = "1.2.1"
$VERSION = 1.002001;
for more reliable version checking with different versions of perl.
140 Add matrix_science::ms_mascotresults::getProteinExpectationValue() and matrix_science::ms_mascotresults::getPeptideExpectationValue()

Version 1.2.1, 15th December 2003

The following items were fixed in this release:

121 Support for tag and etag additions in Mascot 2.0 result files has been added. See for example, matrix_science::ms_peptidesummary::getTagString() , matrix_science::ms_peptidesummary::getTagDeltaRangeStart() and matrix_science::ms_peptidesummary::getTagDeltaRangeEnd()
125 The C++ documentation referred to msparser.h where it should have been 'msparser.hpp'
127 DLLMain is no longer defined in the Windows static C++ libraries.
128 Added matrix_science::ms_mascotresfile::getUniqueTaskID() to support taskid's used by Mascot Daemon in Mascot 2.0
129 Fixed a crash for a faulty results file with the incorrect number of queries.
130 Sort order for proteins with identical scores used to be incorrect with .NET 2003 compiler, and Linux Intel compiler. Code generated by all other compilers was working properly.
132 getAvePeptideIdentityThreshold used to be incorrect for a search that has queries with no matches. Also, added matrix_science::ms_mascotresults::getMaxPeptideIdentityThreshold() as a safer option to display above the histogram on the Mascot 2.0 reports.

Version 1.2.0, 20th October 2003

Support for Java has now been added. See Java toolkit installation for details.

Windows Visual C++ .NET 2003 is now supported along with Visual C++ 6.0. Separate directories are provided for each compiler. The DLLs no longer require Perl to be installed on the computer.

Important Windows Perl users please note that the msparser.dll file is now located in a perl56 or perl58 directory. Do not use the one in the lib directory as this no longer provides any perl support.

The following items were fixed in this release:

5 Proteins with identical scores are now sorted by accesion number. If the accessions contain numbers (e.g. gi numbers), then the sorting is by the actual number. Otherwise, it sorts lexicographically. See also issue #48 below.
15 A warning message is now provided for duplicate accessions. Duplicate accessions are normally an indication of a faulty database, or incorrect parse rules, and should be investigated by the Mascot Administrator.
16 A new function matrix_science::ms_mascotresults::isNA can be called to determine if the search was against a protein database or a nucleic acid database.
36 Peptide mass fingerprint mixture mode is now supported. See Peptide mass fingerprint mixtures
40 and 102 Version information can now be found using the standard perl and java interfaces. Further information can be found at: matrix_science::ms_mascotresfile::getMSParserVersion()
42 Added a function to find number of proteins in the results. see matrix_science::ms_mascotresults::getNumberOfHits()
43 Added two new functions: matrix_science::ms_mascotresfile::enumerateSectionKeys matrix_science::ms_searchparams::getAllUSERParams to get 'user' parameters.
48 For a full protein summary report, the sort order now has a one to one correspondence with the entries in the results file. See also issue #5 above, which affects concise summary and peptide summaries.
49 Added a new function matrix_science::ms_mascotresults::getProteinScoreForHistogram to return the top 50 scores.
50 Issue with symbol log10: referenced symbol not found on some Solaris systems has been resolved.
54 A number of minor problems with the unassigned list have been resolved
56 Added two new functions: matrix_science::ms_inputquery::getPepTol() matrix_science::ms_inputquery::getPepTolUnits()
57 Changed matrix_science::ms_peptidesummary::getProteinsWithThisPepMatch to have an extra default parameter that returns quotes around the accession strings. This is required to allow accessions with spaces.
58 Add matrix_science::ms_protein::getUnmatchedMasses to get the list of observed mass values that failed to get a match to a protein hit in a PMF (listed at end of each hit in a protein summary report).
59 For a peptide summary, the probability cutoff calculation was not the same as in the Mascot 1.9 results reports, which use the average peptide probability. This is always a very minor difference.
60 Calculation for protein score in peptide summary is now exactly the same as in the Mascot 1.9 results reports. This resulted in very rare minor differences.
61 Error handler changes. IsValid() no longer returns false if there are only warning messages. Messages are now classified by severity. The test harness shows new code to print out warnings if the file is valid. Messages no longer have the file name at the beginning.
62 Added new function: matrix_science::ms_searchparams::getElectronMass().
71 Changes to the output of matrix_science::ms_mascotresults::getReadableVarMods for error tolerant search results.
72 Calling getProteinMass used to fail for hit number 50.
74 Option to 'leak bytes' to keep browser connection alive when a report is taking a long time to produce. See: matrix_science::ms_mascotresfile::ms_mascotresfile and matrix_science::ms_mascotresfile::outputKeepAlive()
76 Added a method for getting a protein or peptide summary for single hit very quickly. A parameter 'singleHit' has been added to both matrix_science::ms_peptidesummary::ms_peptidesummary and matrix_science::ms_proteinsummary::ms_proteinsummary.
77 Any SQ always used to return false - even for a sequence query.
78 Added matrix_science::ms_protein::getRMSDeltas to return RMS error for a protein.
79 Proteins in a protein summary are now collapsed by query number rather than peptide string. See Grouping proteins together for further information. This should give compatible results with Mascot 1.9 reports.
81 Key names in the results files are now always matched case insensitively.
82 Sample code for repeating a search is now provided in Perl, Java and C++ in the relevant 'test_' directory. See also Automated repeating of searches
83 Trying to read a result files from Mascot versions earlier than 1.02.00 will now produce an error. These files are not supported.
84 and 85 matrix_science::ms_mascotresfile::getRepeatSearchString used to fail to return the peptol() parameter in cases where an override peptide tolerance had been specified. It also returned seq() instead of comp() for a composition query.
86 Minor differences in the output for an error tolerant search have been fixed.
91 Changed matrix_science::ms_peptidesummary::getProteinsWithThisPepMatch() is now considerably faster
92 Added matrix_science::ms_inputquery::getPepTolString()
93 The parameter minPepLenInPepSummary now behaves in the same way as the Mascot 1.9 reports. In the previous version, peptides shorter than this were totally ignored. Now, they are just ignored for Grouping proteins together purposes.
103 OneInXprobRnd is now a a double rather than an int - it was previously possible to overflow this value.
104 Added a new function: matrix_science::ms_mascotresults::getSequenceMass to calculate the relative mass of a sequence.
110 The function: matrix_science::ms_peptide::getPrettyRank has changed. The ordering of the numbers is now slightly different and is consistent with the original Mascot reports.
113 and 116 A bug in: matrix_science::ms_protein::getCoverage that caused to large a value to be reported (particularly with error tolerant searches) has been fixed. The getCoverage function is not supported for Mixture mode and Unigene - and will return 0 for these results.

Known bugs in Version 1.2.0
39 - Installer required for installing the perl package

Version 1.01, 5th March 2003

The following items were fixed in this release


Unigene indexes are now fully supported. Simply pass the name of the Unigene index file when creating a results object.


matrix_science::ms_mascotresfile::anyMSMS() always used to return false if there was just one query. It now functions properly.


matrix_science::ms_mascotresfile::getRepeatSearchString used to have a line feed at the end of the string, making it inconvenient to use.


matrix_science::ms_peptide::getMrExperimental() can return 0. This is "by design", since it is calculated from getMrCalc() + getDelta(). It is generally recommended that matrix_science::ms_mascotresfile::getObservedMrValue() is used, since this will always return the relative mass, even for no match. Documentation has been updated.


matrix_science::ms_mascotresults::MSRES_REQUIRE_BOLD_RED now functions properly. In version 1.0, supplying the flag had no effect.


The C++ test harness now (optionally) loads parameters from a configuration file. This functionality is solely designed to help in-house testing of the library.


Error messages: ERR_UNASSIGNED_??? were all reported incorrectly. (Message numbers were all out by one).


The documentation is no longer supplied as a pdf file. This help is only available in html format now.
The image for the UML diagram was poor quality in the PDF document - a separate PDF file is now supplied.


"Corrupt" title strings could sometimes be returned by matrix_science::ms_inputquery::getStringTitle(true). Spaces were treated correctly, but other characters such as a parenthesis were not handled correctly. The unescaped string was always returned correctly.


Solaris and Linux versions now available.

Known bugs in Version 1.01
39 - Installer required for installing the perl package

Version 1.0, 28th November 2002

The following items were fixed in this release


Duplicate accession strings in database or repeated peptides in a protein cause confusion. Added matrix_science::ms_protein::getNumDisplayPeptides()


Add function to get the string for a repeat search. See: matrix_science::ms_mascotresfile::getRepeatSearchString()


Documentation addition. Added requirement for

      #define _MATRIX_USE_STATIC_LIB

when compiling under Windows using static library. See Compiler Options


Add "summary" example C++ test file. This outputs a list of of the top matching proteins. C++ example only.


Failure to get protein mass from proteins section. If a protein was in the proteins section, but not in the summary section, then the protein mass was not returned when calling matrix_science::ms_mascotresults::getProteinMass()


Added matrix_science::ms_mascotresfile::getMSParserVersion() to return the Mascot Parser version.

Known bugs in Version 1.0
Bug 1 - Unigene support. Interfaces available, but not yet implemented.

Beta 7, 10th November 2002

The following items were fixed in this release


Supply all (or nearly all!) combinations of C++ static and DLL libraries for Microsoft Windows.


Update the C++ example code documentation.


Infinite loop in perl test harness.

Beta 6, 24th September 2002

The following items were fixed in this release


Backward compatibility - need to know if there is a peptides block. Two new functions should enable this:


Need MinPepLenInPepSummary. There is a new parameter to matrix_science::ms_peptidesummary::ms_peptidesummary.


How to do AUTO. Improved documentation. See the examples.


Null accessions now create an error. See matrix_science::ms_mascotresfile::ERR_NULL_ACC_PEP_SUM and matrix_science::ms_mascotresfile::ERR_NULL_ACC_PROT_SUM.


Error reporting - instead of just keeping one error, have a list of errors. See Error Handling for details.


There is now a way of getting the list of unassigned peptides. See Unassigned peptides list for details.


Need an IsBold function.
See matrix_science::ms_protein::getPeptideIsBold()

13 Need a IsDisplayCheckBox function See matrix_science::ms_protein::getPeptideIsBold()

Beta 5, 13th September 2002
