Error AptamerPool backend using CLI on HPC

[xaimara-santiago]

Hi,

I'm really interested in using the program for my thesis project. I started using the GUI and was able to upload the data but clustering was taking to long and/or crashing, even though I was using just a couple of sequencing files at a time (files stored locally). Also, I was never able to successfully export the data or use it to open the experiment later on, so I had to start from zero every time.
Right now I'm trying to use the CLI to run the program on a high performance computing facility (HPCf). For this, the sequencing files as well as configuration files for each experiment are stored at the HPCf system. When I try to run the -parse command the following error appears within seconds:

I would appreciate any help you could provide.
