Dear galaxy members,

I have a question on the databases used in megablast module from galaxy. There are four db options to blast against with -

1. htgs 28-Jan-2013

2. nt 28-Jan-2013

3. wgs 28-Jan-2013

4. phiX174

Is there any further information to guide which database would be appropriate to use? In addition, how to find the genome information contained in each database?

Many thanks,

Kathryn
