MS::Reader::ProtXML - A simple but complete protXML parser
use MS::Reader::ProtXML; my $res = MS::Reader::ProtXML->new('res.prot.xml'); while (my $grp = $res->next_group) { # $res is a MS::Reader::ProtXML::Group object }
MS::Reader::ProtXML is a parser for the protXML format for storing protein identification in mass spectrometry.
MS::Reader::ProtXML
MS::Reader::ProtXML is a subclass of MS::Reader::XML, which in turn inherits from MS::Reader, and inherits the methods of these parental classes. Please see the documentation for those classes for details of available methods not detailed below.
my $res = MS::Reader::ProtXML->new( $fn, use_cache => 0, paranoid => 0, );
Takes an input filename (required) and optional argument hash and returns an MS::Reader::ProtXML object. This constructor is inherited directly from MS::Reader. Available options include:
use_cache — cache fetched records in memory for repeat access (default: FALSE)
paranoid — when loading index from disk, recalculates MD5 checksum each time to make sure raw file hasn't changed. This adds (typically) a few seconds to load times. By default, only file size and mtime are checked.
while (my $grp = $res->next_group) { # do something }
Returns an MS::Reader::ProtXML::Group object representing the next protein group in the file, or undef if the end of records has been reached. Typically used to iterate over each group in the run.
MS::Reader::ProtXML::Group
undef
my $grp = $res->fetch_group($idx);
Takes a single argument (zero-based group index) and returns an MS::Reader::ProtXML::Group object representing the protein group at that index. Throws an exception if the index is out of range.
The API is in alpha stage and is not guaranteed to be stable.
