@pavel-shliaha Could you please add (by clicking edit) the missing cells? I will add it as man page than.

IdentPeptides.csv

understanding the meaning of some columns will require reading "Database searching and accounting of multiplexed precursor and product ion spectra from the data independent analysis of simple and complex peptide mixtures."

Column Description
protein.Accession UniProt Accession Number
protein.Description Description
protein.dataBaseType Whether the id originates from forward or reverse database
protein.falsePositiveRate false DISCOVERY rate for protein level identifications (calculated as the proportion of proteins idetified from the random database at every point). Waters call it false positive rate, which is an error
peptide.matchType pass 1 (PepFrag1) or pass2 (MissedCleavage; VarMod; InSource; NeutralLoss_H2O; PepFrag2) identifications for more details see the paper above. Note synapter only deals with pepFrag1 or pepFrag2 ids. FDR is calculated separately for pepFrag1 and pepFrag2
peptide.mhp peptide mz (charge corrected)
peptide.seq peptide sequence
peptide.score peptide identification score (see above)
precursor.leID low energy scan ID
precursor.mhp precursor mz (charge corrected)
precursor.retT precursor retention time
precursor.inten precursor intensity
precursor.z precursor charge
precursor.mz precursor mz
precursor.Mobility precursor ion mobility
errorppm ppm error of identifications
pval pvalue of identification calculated by synapter
qval pvalue corrected by syanpter (qval algorithm)
BH pvalue corrected by syanpter (BH algorithm)
Bonferroni pvalue corrected by syanpter (Bonferroni algorithm)
predictedRt predicted retention time after retention time correction
sdRt standard deviation of the retention time prediction
