Are the parcels in the volume or on the surface? If in the volume, then use mri_vol2surf to map them (as a "segmentation") onto the surface, then use mris_seg2annot to create an annotation file. Run either with --help to get docs and examples

matlab is probably the easiest way, but without knowing what format you have them in it isn't easy for us to say. In matlab you can use write_annotation or write_ascii_curv or something to get it into a format we can handle

External Email - Use Caution

Hello Dear Freesurfer Experts,

I have a high resolution brain cortex parcellation that is not extracted from Freesurfer. Now I want to display the nodes(each parcels) on the pial and inflated surfaces. Both pial and inflated surfaces have been extracted from T1mprage image of the corresponding subject using recon-all. Also, the parcels and the T1 image are in the same space. Now, I am wondering is it possible to map these parcels on the Freesurfer pial/inflated surface? By the way, How can I create an .annot file for my parcels? If you could help me with this, I really appreciate your help.

Regards, Mahshid
