[Bioperl-l] remoteblast

Wed May 14 12:18:26 EDT 2014

In this case the code change is straightforward and doesn't require any change to Bio::Tools::Run::RemoteBlast.  The constructor can take a URL_BASE argument, so just pass in the new URL (http://blast.ncbi.nlm.nih.gov/Blast.cgi).  This will overwrite the old URL (http://www.ncbi.nlm.nih.gov/blast/Blast.cgi) hard-coded in Bio::Tools::Run::RemoteBlast.  We made this change to the remote BLAST components in the Pipeline Pilot Sequence Analysis collection and things have been fine.

    my @parameters = ("-prog"       => $program,
                      "-data"       => $database,
                      "-readmethod" => 'xml',
                      "-URL_BASE"   => $url);

    my $blastFactory = Bio::Tools::Run::RemoteBlast->new(@parameters);

Hope this helps.

So the BLAST services changed - not sure if we will still even support perl
based - it will require a developer tracking and testing to the new NCBI
resources since the have discontinued the older submission CGI resource.

You can run remote blast with commandline tool from NCBI as an alternative.

I think we will need to have a developer volunteer who wants to keep
working on tracking the webservices for NCBI to keep this module working.
