Hi Stephane,

According to the SeqIO docs your way should work, so this is probably a
bug. However, Bio::SeqIO can accept a filehandle instead using the -fh
option, so as a workaround you could try something like this:

open my $fh, '|$bgzip -c > $outfile.gz' or die $!;
$seq_out=Bio::SeqIO->newFh(-format=>'fasta', -fh=>$fh);

Cheers,
Roy.
