[Bioperl-l] Error message

[CHANDAN SINGH]

Hi
It seems the 'swall' servertype on EBI no longer exists. May be this  has
already been reported  and debugged. I hope somebody throws light on it.

As for George, if u r in hurry u can use Bio::DB::SwissProt module directly.
Here is a typical code to do this

use strict ;
use warnings ;
use Bio::DB::SwissProt ;
use Bio::Perl ;
my $seq_obj = new Bio::DB::SwissProt('-servertype' => 'expasy' ,
'-hostlocation' => 'us') ;
my $seq = $seq_obj->get_Seq_by_id('ROA1_HUMAN') ;
write_sequence("> roa.sp" , 'fasta' , $seq) ;


See the module for any help .

cheers
Chandan
