When exporting a whole Identification Summary in excel file, the following sheets may be generated (depending on options) :
search settings and infos : Contains information on project and search settings parameters
import and filters : Summary of used parameters during import, filtering and validation process
protein sets : List of all Protein Set, valid or invalidated during
Protein Sets Filtering. Some columns description :
#sequences (#specific sequences ) : number of different peptide sequence identifying the Protein Set (specific : which does not identify any other valid Protein Set )
#peptides (#peptides) : number of different peptide (sequence + PTM) identifying the Protein Set (specific : which does not identify any other valid Protein Set )
#peptide_matches (#specific_peptide_matches) : number of different peptide spectrum matches identifying the Protein Set (specific : which does not identify any other valid Protein Set )
peptides from protein sets : List of best peptide spectrum matches (a single PSM per peptide is listed) for each Protein Set. Some columns description :
#protein_sets : number of Valid Protein Set identified by this PSM.
#protein_matches : number of Protein Match, which belong to at least 1 valid Protein Set, identified by this PSM.
#databank_protein_matches : number of Protein Match, validated or not, identified by this PSM. This is equivalent to the number of protein in fasta files containing the PSM.
protein matches in protein set : list of Protein Matches in each Protein Set. A same Protein Match could thus appears few times if it belongs to different Protein Sets. (same column as protein set)
all PSMs from protein sets : List of all peptide spectrum matches for each Protein Set. (same column as best PSM from protein sets)
statistics : Some statistic values for the exported Identification Summary : number of Protein Set, modified peptides …
