blastp command on the server: the command goes through but the output file stays at 0 B size

Question

[Kayleigh Maier]

Hi all

I am trying to run a blastp search on the university server.

The command I typed in was similar to this:

blastp -db nr -outfmt 5 -query (my query file) -out (my output file name) -num_threads 4

Upon pressing enter, the output file gets created. However, after an hour, the output file was still at 0 B size.

I'm really stuck as to what the issue could be. Any suggestions or help?

Kind regards

Kayleigh

Is the program still running ? The nr database is quite big and and 4 threads are not much. Also check you're not running out of memory.

Thank you. I increased the num_threads to 8, and it is running smoothly.
