Peptide level filters

This page shows an overview of filters, which could be applied to peptide level filtering.

For score filtering, see Score Filters.

filter	short	type	explanation
number of PSMs per peptide	nr_psms_per_peptide_filter	numrical
number of spectra per peptide	nr_spectra_per_peptide_filter	numerical
Accessions	peptide_accessions_filter	literal_list	filters against the accessions in the list of accessions
Description	peptide_description_filter	literal_list	filters against the description in the list of descriptions
File names	peptide_file_list_filter	literal_list	filters against the file names in which the peptide's PSMs are
Missed cleavages	peptide_missed_cleavages_filter	numerical
Modifications	peptide_modifications_filter	modification
Rank	peptide_rank_filter	numerical	filters against the rank, which has to be calculated before
Sequence	peptide_sequence_filter	literal	filters against the amino acid sequence
Source ID	peptide_source_id_list_filter	literal_list	filters against the list of source ID's of the PSMs, not each search engine and peak file combination return valid source IDs!
Spectrum title	peptide_spectrum_title_list_filter	literal_list	filters against the list of spectrum titles of the PSMs
Unique	peptide_unique_filter	boolean	a peptide is considered "unique", if all of its PSMs are unique
