Dear Freesurfer followers/developers,
I am doing a study involving temporal lobes and the parcellations from Desikan and Destrieux atlases have very different results. I like the full gyrus parcellation of Desikan but the temporal pole is very small and limited, while in Destriux the temporal pole is bigger and more appropriate to be studied separately. My question is: can I combine parcellations from these atlases? I.e., if I subtract the temporal pole from Destriuex from the map of Desikan, will I take off all the anterior temporal pole gray matter, or is there any potential mismatch between parcellations so there will remain voxels in the anterior temporal lobe?
Thank you.
P.s. One less important question I have is this. I have noticed that wmparc.mgz is the same as aparc+aseg.mgz with the addition of white matter parcels. For Destrieux there is only the aparc.a2009s+aseg.mgz. Does this file have also the WM parcellation?
