Configuration file for Mascot quantitation methods How to calculate ratio for protein Protein ratio is the median of the peptide ratios Protein ratio is the unweighted average of the peptide ratios Protein ratio is the weighted average of the peptide ratios Data for individual peak Reporter ion m/z Can be variable or exclusive, with maximum of one exclusive group Element for non-SILAC metabolic labelling. Applies to residues only. Data file identifier (replicate) Isotope and impurity correction factors for this component Used to identify this component in the expression for a ratio Specifies which element should be substituted by which isotope. Empty element means "no substitutions". Isotope to be replaced, usually the most abundant natural isotope of the element Isotopic label Unimod composition Chemical element reference Isotope corrrection factor Percentage isotopic impurities for each reagent as tabulated on a Certificate of Analysis.

Ratio to be reported Exclude peptides from quantitation if they contain modifications from this group Sequence qualifier in Mascot notation, e.g. *-TSL Composition qualifier in Mascot notation, e.g. *[C] Quality thresholds for selecting individual spectra or matches Method and parameters to be used to integrate precursor over time. If missing, no integration is performed Method and parameters to be used to remove outliers. If missing, no outlier removal is performed Method of normailsing ratios for a complete data set. If missing, no normalisation is performed How the quantitative information is obtained Descriptive name that will appear in drop down lists, etc. If any modification group specifies exclusive mode, then apply this constraint during the search so that only matches that can be used for quantitation will be returned.
