bioperl ( http://bioperl.org/)模块使用--生物信息学中用的模块
功能:根据核酸的gi号自动从GenBank中提取FASTA格式的序列,可以多序列提取。
QUOTE:#!/usr/bin/perl -w
use Bio::DB::GenBank;
use Bio::SeqIO;
my $gb = new Bio::DB::GenBank;
my $seqout = new Bio::SeqIO ( -fh => *STDOUT, -format => 'fasta' );
# if you want to get a bunch of sequences use the batch method
my $seqio = $gb->get_Stream_by_id ( [ qw ( 27501445 2981014 ) ] );
while ( defined ( $seq = $seqio->next_seq ) )
{
$seqout->write_seq ( $seq );
}
