mri_concat --f pib_lh_fsaverage (textfile of subjects and their images) --o concat_lh_pet.mgh
Should I add -mean here for the GLM? mri_glmfit --y concat_lh_pet.mgh --fsgd pib_fsgd --C group1.group2.mtx --surf fsaverage lh --cortex --glmdir lh.pet.glmdir My simple 2 group-no-covariates FSGD is as follows. Can I also check that it is alright to have the Groups interspersed throughout the order?
