[Bioperl-l] Blast Connection Error

Hello.

Until last two week, I could remote-blast against NCBI nr DB using bioperl
module. But right now, I can not remote-blast since a week.

I had set up interval time as 5 second. In my opinion, NCBI is not allowed
to blast search against NCBI nr DB. If you have experience like me, then
let me know.

Usually I do blast search for 50-100 sequences at one time.

 

The error message is as like this
