I have a fresh install on our cluster.

I'm trying to test out the Megablast tool.  The problem is that
nothing is listed under "against target database".  Where do I get the
target databases and how do I tell galaxy about them?

Thanks,

Greg

Here's what the tool looks like:

Megablast (version 1.2.0)
Compare these sequences:
against target database:
using word size:
Size of best perfect match (-word_size)
report hits above this identity (-perc_identity):
no cutoff if 0
set expectation value cutoff (-evalue):
Filter out low complexity regions? (-dust):
