I have to work with MEGAN on several hundred samples and command line mode is the only option for me.
I work in a network filesystem where computation and storage occur in different servers. I never use MEGAN in my local computer as it is unfeasible to analyze one sample at a time.
So far I have worked in a compute server with the xvfb-run, the problem I have is when trying to run MEGAN in a cluster node with no internet access.
The process starts but stalls after a few minutes and then nothing happens, no error message.
Additionally, if an update is published, the same stalling happens when running MEGAN in command mode with xvfb.
Any suggestions on how to deal with this?
