[Bioperl-l] create Bio::AlignIO object from hash

Actually, I guess some sample code would be more helpful:

use Bio::LocatableSeq;
use Bio::SimpleAlign;
use Bio::AlignIO;
my $seq1=Bio::LocatableSeq->new(-id=>'one', -seq=>'AT-CG', -start=>1, 
my $seq2=Bio::LocatableSeq->new(-id=>'two', -seq=>'A--CG', -start=>1, 
my $seq3=Bio::LocatableSeq->new(-id=>'three', -seq=>'ATTCG', -start=>1, 
my $aln=Bio::SimpleAlign->new(-seqs=>[$seq1,$seq2,$seq3]);
