You can break the annotation into separate labels (mri_annotation2label), then merge the ones you want into a single label (mri_mergelabels), then recombine them into an annotation (mris_label2annot)

Hi Freesurfer Experts,
I was wondering what the best way of combining regions within a parcellation? For example, in the Schaefer 2017 functional atlas, there are regions such as:
7Networks_LH_DorsAttn_FEF_1 0 118 22 0 7Networks_LH_DorsAttn_FEF_2 0 119 17 0 7Networks_LH_DorsAttn_FEF_3 0 119 18 0 7Networks_LH_DorsAttn_FEF_4 0 119 19 0 7Networks_LH_DorsAttn_PrCv_1 0 119 20 0 7Networks_LH_DorsAttn_PrCv_2 0 119 21 0
If I would like to combine all the DorsAttn_FEF areas into 1 node and DorsAttn_PRCv areas into another, what is the best way to do this? I currently have an image that has been parcellated using this atlas that was brought into volumetric space. I would need to have a transformed re-parcellated file and a corresponding color LUT file.
Would appreciate any help, thank you!
Best, Michiko
