CIFTI Pipeline .surf.gii larger than .dtseries.nii

[amirhusseinab]

What happened?

Hi,

After running the CIFTI pipeline with --project-goodvoxels, I tried to load the sub-###_ses-###_task-rest_space-fsLR_den-91k_bold.dtseries.nii on Left and right midthickness surface files inside Workbench View. I got this error:

The CIFTI file contains 32492 nodes for structure CortexLeft but the corresponding surface brain structure contains 232669 nodes.

It seems the surfaces are not in 91k resolution.

Also, an additional question:
Does that "den" indicate denoised? So, there is no need for further denoising (e.g., with XCP-D)?

What command did you use?

fmriprep-v23.2.0a3.simg /input/ /output/ --skip_bids_validation \
--fs-license-file toolboxes/license.txt \
participant --participant-label 3749 \
--output-spaces T1w fsLR MNI152NLin6Asym:res-2 MNI152NLin2009cAsym \
--stop-on-first-crash --nthreads 20 --cifti-output 91k --project-goodvoxels

What version of fMRIPrep are you running?

23.2.0a3

The .surf.gii files here are the subject native surfaces. You will need to use fsLR surfaces with .dtseries.nii.

Thanks for the reply. The only .surf.gii files with fsLR in the analyzed /anat folder are
sub-##_ses-001_hemi-L/R_space-fsLR_desc-reg_sphere.surf.gii,
sub-##_ses-001_hemi-L/R_space-fsLR_desc-msmsulc_sphere.surf.gii

There are no midthickness/pial/white surf.gii files in "fsLR". Even though loading fsLR.dtseries.nii on the above-mentioned sphere surfaces also results in the same previous error. Of note, fmriprep's log file has no errors.
