[Bioperl-l] SeqIO and large GenBank files

[Roy]

Hi everyone,

I want to parse some of the .gbk RefSeq files from ncbi, more specifically,
ref_chr*.gbk.  My script seems to open the sequence stream okay, but when I try
to get the next sequence in the stream, my script spits out a lot of warnings of
subroutine redefinitions.  Is this file incompatible with SeqIO genbank reader?
 Any insight is appreciated, thanks.

Roy

	print $USAGE;
	exit;
}
my $stream = Bio::SeqIO->new(-file => $ARGV[0], -format => "genbank");
my $seq_obj = $stream->next_seq;
exit;
