Sorry for the slow reply. Please capture and send the STDERR from one of the failures.

I've been able to use MPICH to parallelize the first round of <aker, and it will finish in ~2 weeks. However, I'm trying to improve the annotation using SNAP and when I do so every scaffold fails. I'm wondering if you could give me any advice or tell me what I might be doing wrong?
