Hi all, I would like to create my own custom parcellation atlas for the frontal lobes using labels that I have traced on the surfaces. From what I can gather from the mailing list, I need to use mris_ca_train to do this. The usage states indicates I need to specify a canonical surface and an annotation file, but I don't know how to create these. Also, I would have thought I would need to input one annotation file per subject, rather than the single one that is implied in the usage. Do need to do something else before I start using mris_ca_train? Any help is much appreciated. Alex
