No (aparc+)aesg output from fmriprep

Summary of what happened:

Preface: I am new to fMRIPrep.

End goal: Extract timeseries from various ROIs.

Overview: I have run fMRIPrep and there are no errors mentioned in the .html files for each subject. Based on some reading by others on this site and additional information around the internet, it seems like I should be using the (aparc+)aseg files generated by fMRIPrep to created a mask for my data. However, there are no such files in my derivatives directory.

I do have /bids/derivatives/desc-aparcaseg_dseg.tsv and bids/derivatives/desc-aseg_dseg.tsv but no .nii.gz subject specific files.

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

I am using a custom script, which can be found here on Github.

The fMRIPrep command used in this script:

# get subjects
subs=(${bids_dir}/sub-SL*)

for sub in "${subs[@]}"; do
    singularity run --cleanenv -B /data/jdecke5:/data/jdecke5 $HOME/images/fmriprep.simg \
        $bids_dir $bids_dir/derivatives participant \
        --work-dir $work_dir \
        --participant_label "${sub##*/sub-}" \
        --output-spaces T1w \
        --level full \
        --skip-bids-validation \
        --fs-license-file "${fs_license}" \
        --cifti-output 91k

This probably got lost in the refactor. What spaces were they resampled into? I can’t remember off the top of my head where they used to go.

They are pretty easy to pull out of FreeSurfer, though. Here you can resample in MNI with a particular BOLD run to ensure that your voxels align with that run:

mri_convert sourcedata/freesurfer/sub-XYZ/mri/aseg.{mgz,nii.gz}
antsApplyTransforms \
    -i sourcedata/freesurfer/sub-XYZ/mri/aseg.nii.gz \
    -r sub-XYZ/func/sub-XYZ_task-TASK_space-MNI152NLin2009cAsym_res-2_boldref.nii.gz \
    -o sub-XYZ_task-TASK_space-MNI152NLin2009cAsym_res-2_seg-aseg_dseg.nii.gz \
    -n GenericLabel \
    -t sub-XYZ/anat/sub-XYZ_from-T1w_to-MNI152NLin2009cAsym_mode-image_xfm.h5 \
    -t sub-XYZ/anat/sub-XYZ_from-fsnative_to-T1w_mode-image_xfm.txt

If you want them in T1w space, you would do:

antsApplyTransforms \
    -i sourcedata/freesurfer/sub-XYZ/mri/aseg.nii.gz \
    -r sub-XYZ/func/sub-XYZ_task-TASK_space-T1w_res-2_boldref.nii.gz \
    -o sub-XYZ_task-TASK_space-T1w_seg-aseg_dseg.nii.gz \
    -n GenericLabel \
    -t sub-XYZ/anat/sub-XYZ_from-fsnative_to-T1w_mode-image_xfm.txt

Note that with ANTs, you pass the transform to the final target space first, and from the source space last.

@effigies I will test this out, thanks. Is it a problem that I have /bids_root/sourcedata/... and /bids_root/derivatives/sourcedata/freesurfer/...?

Hi @Will_Decker,

Nope! /bids_root/sourcedata/... is for sourcedata for your raw data (e.g., your off-the-scanner DICOMS). Whereas /bids_root/derivatives/sourcedata/freesurfer/... is for sourcedata that go towards constructing derivatives. Having multiple instances of sourcedata is valid and should not confuse BIDS apps. fMRIPrep will default look for and create FreeSurfer outputs in /bids_root/derivatives/sourcedata/freesurfer/, but that can be changed with the --fs-subjects-dir argument.

Best,
Steven

@effigies I was able to successfully execute the commands you provided after some toying around with ther server I am operating on.
