Dear FS experts, There is already a post about that but the concerned person never answered so there is no solution. I’m currently running per-vertex analyses with the --pvr flag of mri_glmfit command. I did correlations between 2 vertex-wise variables correcting for age. I also would like to compare the slope of the pvr between 2 groups: in my fsgd file I have the subject ID and the group. I run the following command: mri_glmfit --y lh.1.448tvs.mgh --fsgd 448_cate30.fsgd --C contrast1.mtx --surf fsaverage lh --cortex --glmdir glm.lh.12_448tvs --pvr lh.2.448tvs.mgh with contrast1.mtx = 0 0 -1 1. I get the following error: ERROR: dimension mismatch between X and contrast contrast1.mtx X has 3 cols, C has 4 cols
Do you know where is my mistake and if it possible to do comparison of the slope of a pvr analysis between groups with mir_glmfit ?
