hi there,

In the code am workiing with i need to usebioperl inorder to reterive te sequence information form the file that i lready have in hand.  
this is the code that i used but it shows some exceptions in the line that I hve quoted below.

my $seqin = Bio::SeqIO->new('./topo_seqs.srs');

and the exception that am getting is:

EXCEPTION: Bio::Root::Exception -------------
MSG: Unknown format given or could not determine it []
STACK: Error::throw
STACK: Bio::Root::Root::throw /jic-atidb/perl/lib/site_perl/5.8.0/i686-linux/Bio/Root/Root.pm:359
STACK: Bio::SeqIO::new /jic-atidb/perl/lib/site_perl/5.8.0/i686-linux/Bio/SeqIO.pm:374
STACK: protein.pl:8

how can i get out of this?
thanks.

It's a specific error from the module (which is not one I'm familiar with). At face value, it appears to be saying that the file you are attempting to read in is not in a format that it recognises.
