mem or disk issue?

[colindaven]

Current Behavior

Plass died. I am unsure whether this is due to a RAM issue or tmp space issue.
Server: 512GB Ubuntu1604.

Failed to mmap memory dataSize=0 File=/tmp/6803214812655189031/nucl_6f_long. Error 22.

Thanks

How does your input data look? What is the average read length?

This error can happen, when the ORF extraction module was not able to extract a single ORF, due to the minimum ORF cutoff.

If your reads are only 100 residues long, then you should use an lower cutoff (something like --min-length 30).

[martin-steinegger]

We intend to fix this in the next release by taking always a fraction of the sequence length as cutoff for the orf extraction.

[colindaven]

Thanks, that got me a lot further. The reads were only 1x75bp. I selected minimum ORF --min-length 20 and got a lot further.

Thanks!

[martin-steinegger]

The sensitivity of Plass can suffer from such short reads because we compute an e-value for the overlap. It is difficult to be significant which such short fragments.
