Howdy,
   Thanks Jen, I will try it tomorrow.

   I installed Blast2Go from the Toolshed in my local instance of Galaxy
and when I try to run it I get the following error:

Index file named 'blast2go.loc' is required by tool but not available.

   I logged as admin and the installation did not gave me any error. From
the terminal:

galaxy.util.shed_util DEBUG 2012-03-23 17:23:37,088 Installing repository

   Anyway, I was thinking to use it because most of my differentially
expressed genes are unknown. I was thinking to use Blast2GO to get them at
least clustered in functional groups. I am not sure if that would be the
best approach to find what might be the function of these genes. I also
checked the list of public services that might have this tool, and Berkeley
BOP is listed, but it seems that they no longer have the server or it was
down when I checked (or the link is broken http://galaxy.berkeleybop.org/).


Thank you.

Luciano
