Hello,
I am deriving a cortical region of interest label from FS from a series of normal controls. I have tried two different methods of obtaining these labels to see which is more consistent but neither are really acceptable.
I am interested in the temporal pole label so first I did the normal mri_annotation2label for each subject but I don't know if it is a problem with segmentation or with vertex assignment, the TP labels can be wide and ranging and not consistent. Additionally, I tried taking the fsaverage subject and doing a label2label to map that TP label on to all the subjects but that was not good either. Does anyone know potentially what the problem can be and do you have any suggestions about how I can automatically derive a temporal pole label without having to get into manually drawing them (which would introduce a whole new array of issues with reliability).
Thank you very much, Kareem
