[Bioperl-l] cdd-search with remoteblast?

Jonas,

If you want to continue to use the bioperl remoteblast interface, probably what you should do is simply call it twice.

Once, as you already know how to do, which will return without CDD results.

Secondly, to get the CDD results, call remoteblast a second time.  This time, using
-database => 'CDD'
-program => 'rpsblast'

However, the wrapper may object to the 'rpsblast' program.  It is not listed in the POD - http://search.cpan.org/~cjfields/BioPerl-1.6.0/Bio/Tools/Run/RemoteBlast.pm)   If so, my guess is that changing the perl wrapper to allow rpsblast will "just work" (tm).  I've cc:ed cjfields at bioperl.org for his opinion on this.

Also, you might want to perform the CDD search first, especially if you are streaming results to eyeball that might like something to look at while the second (presumably longer) search is running.

Cheers,

Malcolm Cook
