MS::Reader::MzIdentML::PeptideEvidence - mzIdentML peptide evidence object
my $pe = $search->fetch_peptideevidence_by_id($EV_ID); say $pe->id; say $pe->start; say $pe->end; say $pe->pre; say $pe->post; say $pe->frame; my $pep_id = $pe->peptide_id; my $db_id = $pe->search_db; my $is_decoy = $pe->is_decoy; my $tbl_id = $pe->trl_table;
The MS::Reader::MzIdentML::PeptideEvidence class represents a <PeptideEvidence> element in the search results. This links peptide sequences to their location in a database protein, as well as including other information such as decoy status.
MS::Reader::MzIdentML::PeptideEvidence
my $id = $pe->id;
Returns the peptide evidence ID, which is a unique identifier within the results file
my $pep_id = $pe->peptide_id; my $pep = $search->fetch_peptide_by_id( $pep_id );
Returns the ID of the associated Peptide element, which can be used to look up a corresponding MS::Reader::MzIdentML::Peptide object.
MS::Reader::MzIdentML::Peptide
my $db_id = $pe->search_db;
Returns the ID of the search database the evidence comes from.
my $start_loc = $pe->start; my $end_loc = $pe->end; my $prev_aa = $pe->pre; my $next_aa = $pe->post;
Return information related to a peptide's context within it's parent protein: start coordinate, end coordinate, previous amino acid, and subsequent amino acid. None of these values are guaranteed to be defined.
my $reading_frame = $pe->frame;
The translation frame of the peptide, in the range of -3 to -1 or 1 to 3. Not guaranteed to be defined.
next if ($pe->is_decoy);
Returns a boolean value indicating whether the peptide evidence is from a decoy protein.
my $tbl_id = $pe->trl_table;
Returns the ID of the translation table associated with the peptide evidence.
The API is in alpha stage and is not guaranteed to be stable.
