I want to add some functionality to my website, that is similar to "Retrieve results for an RID" of NCBI blast. In other words i am trying to retrieve blast results using a particular rid.


following is the code: 
----------------------------------------------------

my @params = ( '-prog' => 'blastn',
               '-expect' => 1,
               '-readmethod' => 'SearchIO' );
               
               
my $factory = Bio::Tools::Run::RemoteBlast->new(@params);

my $rc = $factory->retrieve_blast($rid);

----------------------------------------------------

[download]
$rid is a legitimate request ID that is passed as parameter to the function.
retrieve_blast function returns Bio::SearchIO::blast=HASH(0x2c9bf8), that indicates the success.

but $rc->next_result() function fails and I get the following error.

------------- EXCEPTION -------------
MSG: no data for midline genome
STACK Bio::SearchIO::blast::next_result
/usr/perl5/site_perl/5.6.1/Bio/SearchIO/blast.pm:1151
STACK main::test_blast /var/apache/cgi-bin/user/blast.pl:578
STACK toplevel /var/apache/cgi-bin/user/blast.cgi:65

--------------------------------------

How can I do this.

Thanks.
