You should make sure your replies are sent to the list, as you're likely 
to get a faster response.

No, the -file option of SearchIO->new() takes, unsurprisingly, a 
filename. I'd tell you to pay careful attention to the docs, but sadly 
the RemoteBlast docs are currently wrong.

submit_blast() claims to return 'Blast report object' (which in any case 
certainly wouldn't be a filename) when in fact it returns, as you 
discovered, a (for our purposes) meaningless number.

As I suggested before, you need to look at the synopsis for 
Bio::Tools::Run::RemoteBlast instead.

(having called submit_blast you must do the each_rid loop)


Does anyone care to go through the POD for RemoteBlast and update it to 
an accurate state?
