LINDA with singularity and batch processing with slurm

[tib-sim]

Hi - I wonder if someone already tried to used LINDA on singularity and use the BATCH processsing with slurm?

I tried the slurm code below with a R script encompassing the required lines of command to start LINDA.

So far, I have an error saying that the file does not exist while I have specified the right path.

#!/bin/bash

#SBATCH --job-name=linda
#SBATCH --output=./log/linda.out
#SBATCH --error=./log/linda.err
#SBATCH --cpus-per-task=10
#SBATCH --mem=40G

WD="/my/working/directory"

LINDA_SINGULARITY_IMG="/directory/to/linda/image/linda_latest.sif"
SCRIPT_R=${WD}"/LINDA_script.R"

srun singularity run --cleanenv --bind ${WD}:/home ${LINDA_SINGULARITY_IMG} Rscript SCRIPT_R

I have not used it myself slurm, maybe SGE long time ago. I also have not used it through containers. Not sure if anyone else has done it.

You probably need to go step by step, make sure it works with singularity in a regular shell instead of slurm job. Your script must point to the container folders you are binding. If you manage to get it to work, sending slurm jobs will be a natural extension.

Out of curiosity, I am a big fan of containers for reproducibility purposes, but why are you trying to go through containers in this case? Might as well call the jobs through a regular Linda installation in the hpc.

Hi - Thanks for the prompt reply.

I understood my mistake the line srun singularity run --cleanenv --bind ${WD}:/home ${LINDA_SINGULARITY_IMG} Rscript SCRIPT_R has to be edited as follows srun singularity run --cleanenv --bind ${WD}:/home ${LINDA_SINGULARITY_IMG} Rscript ${SCRIPT_R}

Actually I am using the container because R is not installed on the hpc and seems it takes some time to the IT team of my instution to install it. I did not want to wait too long before starting to play around with LINDA (looks like a very nice tool btw!). That is the main reason. Also with all the admin rights I am not sure how easy it would be to install R libraries so it is possible I'll stick with the container because it will make my life easier.

Also, I saw in an other issue raised the possibility that LINDA could become a BIDS-app, is there any update on this side?

Best, Simon

No, sorry, I have not planned to work on the bids app for now, but will see about it later.

Fyi, R packages do not require admin privileges, they will be installed in your home folder. You may not even need admin to install R, but I am not sure of that.

Please let the community know imhere if you make it work, so others can learn.

One more question. Where did you find the singularity image? Converting from docker typically requires admin privileges.

Ok thanks for the information, I am still not super familiar with the hpc. Actually in my former institution I was not allowed to use sudo on the hpc. It looks like I have some admin rights on the hpc of my current institution so maybe it is possible to install R on my own.

Given I have been able to use batch processing to run 2 subjects in parallel on the hpc I think I will stick using the containers.

To get the image I ran the command singularity pull docker://dorianaps/linda:latest. I don't think I need admin right to get it. At least I was able to get singularity images on the hpc of my former institution as well. Maybe they restricted the use of sudo only. I am not so sure to be honest.
