NAME

FAST::Bio::AlignIO::meme - meme sequence input/output stream

SYNOPSIS

Do not use this module directly. Use it via the FAST::Bio::AlignIO class.

  use FAST::Bio::AlignIO;
  # read in an alignment from meme
  my $in = FAST::Bio::AlignIO->new(-format => 'meme',
                             -file   => 'meme.out');
  while( my $aln = $in->next_aln ) {
     # do something with the alignment
  }

DESCRIPTION

This object transforms the "sites sorted by position p-value" sections of a meme (text) output file into a series of FAST::Bio::SimpleAlign objects. Each SimpleAlign object contains FAST::Bio::LocatableSeq objects which represent the individual aligned sites as defined by the central portion of the "site" field in the meme file. The start and end coordinates are derived from the "Start" field. See FAST::Bio::SimpleAlign and FAST::Bio::LocatableSeq for more information.

This module can only parse MEME version 3.0 and greater. Previous versions have output formats that are more difficult to parse correctly. If the meme output file is not version 3.0 or greater, we signal an error.

FEEDBACK

Support

Please direct usage questions or support issues to the mailing list:
