nohup not helping in Helixer.py, run is stopped when connection is lost about helixer HOT 5 OPEN

Hi, yeah, I am unaware of any interaction between Helixer and nohup, and such an interaction would be surprising.

I would hazard a guess the run could be failing for a different reason on the larger genome, and nohup is only obscuring the output.

Thus I agree with the comment from @nhartwic, which importantly includes an example on how to differentiate standard error and standard out with nohup. Were I running this, I might further change 2>&1 to 2>Taestivum.Chinese_Spring.HPIv02.err or similar, just for my own organization. Then the useful error messages would be in Taestivum.Chinese_Spring.HPIv02.err.

I can also only second @colindaven's advice on using tmux or screen. Either of those will make remote work easier, in general.

Thank you all for the advice and discussion. I know that nohup is expected to work, possibly my set up was not the optimal. I will try what you suggest in future helixer runs and come back to this thread with updates!

I'm not the dev.

I've been running helixer using singularity and have encountered no issues backgrounding and nohuping. Example execution below...

nohup singularity run --bind /data1:/data1 --nv helixer-docker_helixer_v0.3.2_cuda_11.8.0-cudnn8.sif  Helixer.py \
    --fasta-path Taestivum.Chinese_Spring.HPIv02.fasta \
    --gff-output-path Taestivum.Chinese_Spring.HPIv02.gff3 \
    --lineage land_plant \
    --species Taestivum.Chinese_Spring.HPIv02 \
    > Taestivum.Chinese_Spring.HPIv02.log 2>&1 &

If I were you, I'd double check the commands you are using, then double check your environment and relevant bashrc/login/whatever. And I guess also try the containerized version of Helixer if you haven't?

IDK. Just trying to be helpful.

Nohup should work, but try using screen or tmux as an alternative. I haven't seen any problems like this running helixer via a nextflow pipeline using a singularity container.

@alexandrosbousios you might need to also google ssh keepalive and look into associated answers if this issue persists, but it is related to your infrastructure and nothing to do with helixer.
