Hello FreeSurfer experts,

I'm attempting to obtain volume values for the ROIs, each corresponding to a specific network based on Yeo's 17 Network atlas.

Here are the steps I've done so far:

1. Transform from fsaverage to subject's surface (LH, RH)
mri_surf2surf --srcsubject fsaverage5
--trgsubject sdas/sub052
--hemi lh
--sval-annot 1000subjects_reference/Yeo_JNeurophysiol11_SplitLabels/fsaverage5/label/lh.Yeo2011_17Networks_N1000.annot
--tval $SUBJECTS_DIR/sub052/label/lh.Yeo_17Network_native.annot

2. Transform from subject's surface into my subject's volume
mri_aparc2aseg
--s sub052
--o $SUBJECTS_DIR/sub052/mri/Yeo17.mgz
--annot Yeo_17Network_native --annot-table Downloads/1000subjects_reference/Yeo_JNeurophysiol11_SplitLabels/MNI152/17Networks_ColorLUT_freeview.txt

Upon inspecting the output file (Yeo17.mgz) overlaid with 17Networks_ColorLUT_freeview.txt before extracting the volume values, I observed that the actual ROI doesn't match the label.

ex) The label indicates "DefaultB_IPL" when I point the caudate nucleus

Is there something I might be missing?

And would you let me know how to extract the volumes of the ROIs for each of the 17 Networks?

So I would be getting volumes for 114 ROIs in total.

I would greatly appreciate your help.

Jihye
