When I parse an alignment created by lalign which is included in FASTA36, I got errors. We got two sequences in each fasta file now, but if one sequence each, there's no error. Here are the codes and error.

@lalign36 -m 10 at.fasta os.fasta >test.aln@

@from Bio import AlignIO
handle = open('test.aln')
for a in AlignIO.parse(handle, "fasta-m10"):
    assert len(a) == 2, "Should be pairwise!"
    print "Alignment length %i" % a.get_alignment_length()
    for record in a:
        print record.seq, record.name, record.id
@
