Bio::AlignIO::maf - Multiple Alignment Format sequence input stream
Do not use this module directly. Use it via the Bio::AlignIO class.
use Bio::AlignIO;
my $alignio = Bio::AlignIO->new(-fh => \*STDIN, -format => 'maf');
while(my $aln = $alignio->next_aln()){
my $match_line = $aln->match_line;
print $aln, "\n";
print $aln->length, "\n";
print $aln->num_residues, "\n";
print $aln->is_flush, "\n";
print $aln->num_sequences, "\n";
$aln->splice_by_seq_pos(1);
print $aln->consensus_string(60), "\n";
print $aln->get_seq_by_pos(1)->seq, "\n";
print $aln->match_line(), "\n";
print "\n";
}
This class constructs Bio::SimpleAlign objects from an MAF-format multiple alignment file.
Writing in MAF format is currently unimplemented.
Spec of MAF format is here:
