in reply to how to merge the files of DNA sequences?
Of course if you wanted to have sequence data in another file format you just have to change the 'fasta' to something else like 'genbank', 'swiss', 'embl', etc...use strict; use Bio::SeqIO; use Bio::Seq; my %seqs; my @files = qw(file1 file2); for my $file ( @files ) { my $in = Bio::SeqIO->new(-format => 'fasta', -file => $file); while( my $seq = $in->next_seq ) { $seqs{$seq->display_id} .= $seq->seq; # append the seqdata } } my $out = Bio::SeqIO->new(-format => 'fasta', -file => '>newfile.fa'); while( my ($seqname,$seqstr) = each %seqs ) { my $seq = Bio::Seq->new(-id => $seqname, -seq => $seqstr); $out->write_seq($seq); }
