FMRIPREP errors during freesurfer recon-all or during ICA-aroma

fmriprep

#1

Hi there,

I’ve started using fmriprep very recently to preprocess my data on our lab’s Linux cluster. I am encountering several issues and I am trying to determine if they are due to bugs in the pipeline or to computing issues related to the clusters.
So far, I’ve mainly tried to only run one subject at a time (or max 1 subject per node).

I am using FMRIPREP version: 1.0.6-2, from a singularity container, and my fmriprep command is as follows:

singularity run /home/ccharpen/fmriprep/poldracklab_fmriprep_latest-2018-01-30-2863112d2d8d.img -w /home/ccharpen/ObsLearn/prepdata/work /home/ccharpen/ObsLearn/rawdata/rawBIDS /home/ccharpen/ObsLearn/prepdata/fmriprep participant --participant-label 007 --ignore slicetiming --use-aroma --ignore-aroma-denoising-errors --fs-license-file /home/ccharpen/fmriprep/license.txt

So far, out of 7 subjects, one has succeeded on the first try. For all the others, it’s either crashing during freesurfer surface reconstruction or during ICA-AROMA for one or more functional runs (see error messages below).

At first my guess was that it was maybe a memory error since those processes seem to be the heaviest in terms of memory usage. Also our HPcluster is set up to kill jobs when they go over the requested memory for that job (which I had specified at 6GB); but when trying to re-run them with either 24GB or 32GB, some subjects ran but some others still crashed - which makes me think there is more to it than memory…

Any thoughts?? Let me know if you need more information!

Thanks,
Caroline

The first error seems like a filesystem issue. Is it reproducible (as in if you run the same subject again does it break in the same way)?

The ICA AROMA bug is a known issue - you can track our progress on it here: https://github.com/poldracklab/fmriprep/issues/981

BTW - did you run bids-validator on the input data? Your TR is exactly 1.0s which is unusual…


#3

Thanks for your reply!
I did run bids-validator on the input data, and there were no error - I double checked my protocol anyway and my TR is indeed exactly 1.0s (I am using multiband).

Re- the first error, I re-ran the subject and it ran through without error, which probably means it was indeed a filesystem issue. However, I am now getting a mask problem for one of the functional runs, whereby the brainmask file for that run has a big hole in it, even though both the preproc BOLD and the AROMA-denoised timeseries look just fine!

This is the fmriprep output showing the hole in the mask:

Any idea why this could be happening? At what point is the functional mask being created? I am guessing this could be a problem for the confounds estimation and ICA, since those will only be estimated within the mask? What would be the best way to re-run that part?

As for the ICA-AROMA bug, good to know that this was known - I will definitely track the process.
I also noticed another type of error at the time of the ICA, but not sure yet if this is reproducible or not, so I will try to run that subject again:

#4

The mask/report issue was resolved in the latest version of FMRIPREP - please try 1.0.8


#5

Hi @ccharpen, could you try the poldracklab/fmriprep:1.0.12-dev0 docker image and check whether the ICA-AROMA errors are fixed for you?

Thanks very much!


#6

Hi! So I just tried running 1.0.12-dev0 on one subject for which I had the two ICA-AROMA errors (i.e. “TypeError: len() of unsized object” for one of the runs and “ValueError: invalid literal for int() with base 10: ‘’” for 2 of the runs).

I now have only one error left (“ValueError: invalid literal for int() with base 10: ‘’” for one of the runs). So I guess this is definitely a move in the right direction, as the first error is gone; however the second one still remains for one of the runs. Here is what I get in the log:

I will try to re-run that same subject to see if it reproduces, and also another subject or two who also showed errors.

Thanks!


#7

Okay, we released version 1.0.12 and that one should fix for this problem. Please let us know if it was indeed solved.


#8

Ok, good to know - I will try the new version.

In the meantime, I also noticed that the classification definitely fails for some subjects/runs - as in many noise components classified as signals OR (more problematic) signal classified as noise.

See below for an example of each - this is from the same subject, two different runs:

I am wondering if something is wrong with the classifier… Any chance that this might be fixed in the new version as well?

Thanks!

This particular answer (and probably the whole thread) will probably be of your interest.

EDIT: Let’s keep this conversation there, if you don’t mind :slight_smile:
