Using too much RAM (memory)

[kopardev]

Running NCLscan on our HPC runs into memory issues. The dashboard plots look like this:

Any idea what is happening and how to get around this issue?
Host is hg38 + a few viruses (well annotated).

Hi,

It may be caused by the mp_blat.py, I guess.

mp_blat.py is just a wrapper for applying multiple blat processes, not a real parallelized version of blat,
so the maximum memory usage would be equal to 4GB * mp_blat_process.
("4GB" is for human genome, and the mp_blat_process is a parameter in the NCLscan.config, which is for tuning the number of proceses for mp_blat.py)
