PSMs

The ‘Peptide View’ tab includes the information at PSM level for every peptide. The Peptide Table panel shows for each peptide the list of PSMs with the corresponding scores from the search engines, the list of modifications, Precursor charge and precursor mass. In the example ech PSM contains the information of the OMSSA and XTandem Score, also the table provides the information of the peptide sequence length; start and end position in the protein sequence.

Peptide Information

The Peptide Table also provides the information about each protein identified in the file. It provides information about the peptide sequence, Protein identifier, sequence length, isoelectric point, number of PSMs, and modification summary.

Protein Information

The protein panel shows all the information about identified proteins: protein level scores, protein sequences, protein identifier, number of PSM for each protein, modifications and number of unique peptides. The first column is a three table structure when the protein inference is provided (), if the use click in the sign the group is collapsed.

Finally, the sequence coverage is shown in a column for each protein:
