You'll have to sample your volume-based segmentation onto the surface using mri_vol2surf (you might have to play with the projection fraction). Then use mris_seg2annot. If you run it with --help, you will get an example. The tricky part is getting the color table set up correctly

External Email - Use Caution

Dear Freesurfer Experts,

I would like to divide the surface parcellations of the neonatal brain. The parcells were extracted using Draw_EM (Developing brain Region Annotation With Expectation-Maximization), an atlas based segmentation, from cortical and sub-cortical. As I understand from help comments, mris_divide_parcellation would help, but it needs annotation file to be imported as input. I do not have the annotation file. I would appreciate it if you could help me how to divide my parcells in more regions?

Regards, Mahshid
