Hello, Thanks Doug for your help on this previously. I am quite puzzled by the vertex-wise local correlations that I've found (i.e more tau thicker cortex)... and before I go down the rabbit hole of trying to dissect what could be happening, I'd like to check if one of the steps in my workflow has gone wrong?
1) My FSGD is a simple one group design with no other covariates. 2) mri_concat --f stacks_cth_rh15 --o concat_cth_rh15_.mgh **stack of thickness maps after qcache 3) C_pvr_cth.mtx = 0 1 4) mri_glmfit --y concat_tau_lh_sm8.mgh --pvr concat_cth_lh15.mgh --fsgd FSGD_tau dods --C C_pvr_cth.mtx --surf fsaverage lh --cortex --glmdir pvr_lh.glmdir Thanks a lot! :) Best Wishes, Elijah Writing results C_pvr_cth maxvox sig=4.6783 F=34.7936 at index 31050 0 0 seed=1479612145 mri_glmfit done Thanks a lot for your help.
