you can use CAT12’s Surface Calculator You either find it on the CAT12 GUI, i.e. CAT12 -> Surface Tools->Surface Calculator, or via SPM12->Batch->SPM->Tools->CAT12-> Surface Tools->Surface Calculator. It works similar to spm_imcalc.

I am currently attempting to create a whole brain image displaying the percent relative difference in cortical thickness from one subject scanned in 2013 and again in 2019. The thickness file is a GIFTI file, which ImCalc cannot run suface level calculations on. If anyone is familiar of a CAT12 function that can perform this task, your advice would be greatly appreciated.
