[Bioperl-l] If you use RemoteBlast

[Barry Moore]

Jason-

I stepped through the code in
Bio::Tools::Run::RemoteBlast::submit_blast, and bioperl is using the
default new formatter, and for the dozen or so nucleotide sequences that
I ran no problems parsing.

So those of you who use the Tools::RemoteBlast module, please read  
the following email.    We need some people to test out how much the  
parser breaks with the "new" formatter. Tests seem to pass right now,  
but I don't know if that is because the 'old' format is being  
requested still.  Could someone please take a little time to see  
what's going on and report back.

Thanks,
