Could you please type in your Matlab command's line the following:

  info = conn_bidsdir('...\derivatives\fmriprep');

  save temporalfile.mat info;

(changing the ...\derivatives\fmreprep bit to the actual location of your fmriprep folder) and then send me that temporalfile.mat file so I can take a look at the contents of your folder structure and see if that helps me figure out why CONN is not importing any files?

Dear CONN community,

I am currently trying to use the automatic import function in:

Project → New (import) → From fMRIPrep dataset

However, the importer does not create any subjects.
When I select my fMRIPrep root folder, CONN shows something like:

“1 folder selected, XXXX matching files”

but after clicking OK, nothing happens and no data are imported. No error message appears.

 

Folder structure

My fMRIPrep output is located in:

...\derivatives\
      fmriprep\
          dataset_description.json
          sub-01\
              anat\
              func\
              figures\
              log\
          sub-02\
              anat\
              func\
              figures\
              log\
          ...
          sub-15\

The folder name is exactly fmriprep, and dataset_description.json is directly inside this folder (not inside subject folders).

Filename structure

Originally, subjects were named like sub-VP105, so I renamed them to numeric BIDS-style names:

sub-01_task-RS1_space-MNIPediatricAsym_cohort-6_desc-preproc_bold.nii.gz
sub-01_task-RS2_space-MNIPediatricAsym_cohort-6_desc-preproc_bold.nii.gz

I am using the NIH Pediatric MNI template (MNIPediatricAsym) from fMRIPrep.

Manual loading of functional and structural files into CONN works without issues.
Only the automatic fMRIPrep importer does not detect any subjects.

I would like to use the automatic importer for a larger dataset (≈90 participants), so understanding why my current dataset is not detected would be very helpful.

Thank you very much!
Ricarda

thank you so much for your response. I attached the temporalfile.mat file and am looking forward to your suggestions. Thanks again!
