I am trying to use dcmunpack to transform dicom images to a nifti format inside a FSFAST formatted directory (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/fsfastrestingstatetutorial), however I am having issues understanding how to use properly the -run argument.

This is the command I am trying to use:

dcmunpack -src  fMRI_dir  -targ sessionid -fsfast -run 2 rest nii.gz f.nii.gz

I assume I am making some mistakes with the command, specially with the run arguments since this is the error that I got in the terminal: ERROR: could not find run 2 in data

My directory contains fMRIs downloaded directly from the ADNI database and grouped in folders following this structure:

/fMRI_dir/subject_id/Axial_rsfMRI/date/image_uid/dicom images

I've searched the list and no similar errors have been reported. Does anyone have any thoughts on how to solve this?

1) FreeSurfer version: freesurfer_ubuntu20-7.4.0_amd64.deb
2) Platform: Ubuntu 20.04 in WSL

Thanks for your help.
