External Email - Use Caution
Hello,
I am currently working with the fsaverage7 parcellation and would like to move to a lower resolution brain parcelltation (fsaverage4, 5, or 6 for example). I was wondering if there is a simple way to translate my data without rerunning recon-all? So essentially, is there a way to turn fsaverage7 parcellation into 6 or lower?
Best,
Alex
Hi Alex
yes, the vertices of the lower res fsaverage representations come first in the ordering. So the first 12 are ico0, then the first 42 are ico 0 and ico 1, etc....

You can use mri_surf2surf or mris_apply_reg to do the transferring
