Summary of what happened:

Hello everyone,
I am trying to run fMRIprep using Neurodesktop App on my Windows workstation. I am using the following script, but it throwing me an error. It seems like the problem stems from accessibility to the freesurfer, but I am not sure.
Could someone help?

Command used (and if a helper script was used, a link to the helper script or the command generated):

#!/bin/bash


#User inputs:
bids_root_dir=/home/jovyan/neurodesktop-storage/fmri_classifier
subj=001
nthreads=4
mem=20 #gb
container=docker 

#Begin:

#Convert virtual memory from gb to mb
mem=`echo "${mem//[!0-9]/}"` #remove gb at end
mem_mb=`echo $(((mem*1000)-5000))` #reduce some memory for buffer space during pre-processing

export FS_LICENSE=/home/jovyan/neurodesktop-storage/license.txt

#Run fmriprep
  fmriprep $bids_root_dir/nifti $bids_root_dir/derivatives \
    participant \
    --participant-label $subj \
    --skip-bids-validation \
    --md-only-boilerplate \
    --fs-license-file /home/jovyan/neurodesktop-storage/license.txt \
    --output-spaces T1w MNI152NLin2009cAsym:res-2 \
    --nthreads $nthreads \

Hi @VinodhKumar,

In the future, please use the Software Support post category which provides a post template for you to give us important information. You can see I added it in for you here, but there’s still some info missing you provide by editing your post.

In regards to your problem:

Try upgrading to most recent version (23.2.1 at this time).

You say you’re using docker, but the lack of docker preamble suggests you are running in a bare-metal python installation. Unless is there something about Neurodesktop I am missing?

Are the data BIDS validated? Can you tell us the BIDS validation report?

Can you manually specify a freesurfer subjects dir that you know exists with the --fs-subjects-dir argument?

Best,
Steven
