Dear Gian,
if you use a newer CAT12 version it will automatically recognize that the images are already skull-stripped. To be on the safe side you can call CAt12 in expert mode and set the option for "Skull-Stripping" to "none (already skull-stripped)".
Best,
Christian

I would like to use CAT12 to segment the GM, to create thickness and gyrification maps. Does the segmentation work if the input images are only brain tissue without the head? And in case, is there a way to make it work?
