[Bioperl-l] Closing a SeqIO filehandle

[Nancy Hansen]

Hi!

	I can't figure out how to close the filehandle of a Bio::SeqIO
object within my program.  I'd like to create fasta files, and then allow
another program (called from my program) to open them.  When I do
something simple like

my $out_fasta = Bio::SeqIO->new(-file => ">$filename",
                                -format => 'Fasta');
$out_fasta->write_seq($seq);
exec "$cm_exe $filename";

The program I call doesn't see the final partial block that I suppose is
still in the buffer.  Is there any way to flush and close the filehandle?

	Thanks,
	--Nancy
