You can use mri_vol2surf to sample it on the surface, then use
mris_seg2annot to create an annotation with it. BTW, you can probably
just use the output of mri_vol2surf in your matlab program instead of
the hassle of working with annotations

Dear Freesurfer community,
apologizes in advance for what may be a simple question.
I have a volume region of interest file in .nii format. I would like
to do a surface functional connectivity analysis in a MATLAB toolbox,
and to do so, I would need to somehow convert this volume ROI to an
.annot file.
I was wondering if Freesurfer has any tools to do this?
Could it be accomplished using a combination of mri_vol2label and then
mri_label2annot?
Best,
Paul
