Permission denied to /tmp?

Not sure if this is related to other permissions issues recently, but I thought not as I’m running 1.2.6 rather than the newer 1.3.0 to maintain consistency with a previous batch of subjects. Every other job (at least, thus far), gives the error below, PermissionError: [Errno 13] Permission denied: '/tmp/fmriprep_wf/index.html'. Some subjects seem to work, and others don’t. I didn’t have this problem previously. Is this something at the level of my HPC that I should investigate, or related to fmriprep?

I’m running with the flag -w /tmp, as running without it writes to my /home directory and rapidly fills it up.

Update: In desperation, I tried changing permissions on the input data to world-read and writable, but no difference. The same subjects continue to fail.

Many internal operations of *fMRIPrep* use
*Nilearn* 0.5.0 [@nilearn, RRID:SCR_001362],
mostly within the functional processing workflow.

Hi @Ursula_Tooley

May you please share what your input command is? I am assuming you are running this using singularity?

Yes, @franklin, so sorry–I totally forgot about that and edited to add the working dir to the original post, but the whole command is below. Running through singularity on an HPC as an array job, 4/7 of the jobs work just fine, 3/7 fail with this error.

unset PYTHONPATH;
echo 'job is running'
singularity run --cleanenv -B ${BIDS_folder}:/mnt ${tools_dir}/fmriprep-1.2.6-1.simg \
/mnt/ /mnt/derivatives \
participant \
-w /tmp \
--participant-label ${subject} \
--fs-license-file $HOME/license.txt \
--use-aroma \
--output-space T1w template fsaverage5 \
--cifti-output \
--nthreads 1 \

Thank you for sharing your command! I am thinking it could be server permissions issue depending on the ownership of the /tmp folder (i.e. needing to have root permissions on the HPC). Are you the owner of the /tmp folder (vs. having just read/write on it)? Though interesting that it works for some runs, but not for others. Is there something different between the subjects that work and don’t work?

As you said above there are some leftover issues with this version so it would be interesting to see if a current version would solve this problem, but understand your version constraints.

I can’t figure out any differences between the subjects it works for and those it doesn’t–believe me, that was the first thing I thought of! I thought it must be permissions but couldn’t think why half of them would work, in that case.

Having a working directory somewhere bound to the singularity container (in /derivatives for example) seems to fix the issue, but it’s very odd. I’m building the latest container and if I end up trying it, I’ll post again.

Permissions can be a weird issue! I found a couple issues that when using -w with a bound directory it worked (in that case it was calling docker), but interesting it works for singularity too! (this issue had the same Error 13 you have). Sounds good!

I wonder if perchance your jobs might be running on a node someone else is running FMRIPREP on in /tmp. If the other person created the /tmp/fmriprep_wf folder you would not have permission to it. Could you try running:

unset PYTHONPATH;
echo 'job is running'
singularity run --cleanenv -B ${BIDS_folder}:/mnt ${tools_dir}/fmriprep-1.2.6-1.simg \
/mnt/ /mnt/derivatives \
participant \
-w /tmp/utooley${subject} \
--participant-label ${subject} \
--fs-license-file $HOME/license.txt \
--use-aroma \
--output-space T1w template fsaverage5 \
--cifti-output \
--nthreads 1 \

I wonder whether /tmp is automatically bound on your singularity installation. If not, this permission denied would be expected because paths in the singularity image are read-only. Only paths made accessible from the host can be written (singularity automatically sets some mount points). Can you try the following?

singularity run --cleanenv -B ${BIDS_folder}:/mnt -B /tmp:/tmp \
                 ${tools_dir}/fmriprep-1.2.6-1.simg \
                 /mnt/ /mnt/derivatives \
                 participant \
                 -w /tmp \
                 --participant-label ${subject} \
                 --fs-license-file $HOME/license.txt \
                 --use-aroma \
                 --output-space T1w template fsaverage5 \
                 --cifti-output \
                 --nthreads 1

I tried the command @ChrisGorgolewski posted, and it worked (meaning it continue to run past the writing of index.html). Given that I was running my jobs in an array, I could have been the other user writing to /tmp/fmriprep_wf, right? Except I guess then I’d have permissions for that folder, so wouldn’t have run into this issue. I guess this is a good enough workaround for now, I’ll repost if it continues to occur (it’s happened with participants from two different datasets now).

I think @oesteban, if /tmp weren’t automatically bound on my singularity installation, then none of my jobs would work (correct me if I have this wrong). It’s puzzling mostly because some jobs ran and some didn’t.
