[maker-devel] Maker error after calling SNAP

[Decker, Samuel]

Hi,
I am trying to run maker on Camelina Sativa, and it runs smoothly for the most part until it reaches a certain stage in SNAP.  Maker passes a short sequence to SNAP to predict genes on, but that sequence is more than half N's, and SNAP fails, leading to maker calling that chunk as a failure and ending the run.

When looking at the Widget call, it seems that for some reason the .hmm file is not included in the command sent to SNAP.  I manually ran the command with the .hmm file included and it seems to execute, though no output file is produced.

After speaking with Ian Korf, he seemed to think it was an error relating to the very short and ambiguous (many N's) fasta file that maker passed to SNAP.

So two questions: Why did the .hmm file not get passed to SNAP as part of the command, and why did maker send such a short chunk to SNAP for gene prediction?

I've attached a text file with the command and the error log, the fasta that maker is sending to SNAP, and the xdef file as well.

Thank you for your help,
