Hi Ricky how did you try to load the defect_labels? The end of the recon-all.log file lists a defect with 26K vertices, which is probably too big to fix (it's about 1/5 of a normal surface). You should be able to visualize it by loading the lh.defect_labels file as an overlay on the lh.inflat

It looks like you are using gender as a continuous variable. You should set up two classes, one for male one for female. You can then test for the AT slope with a contrast of 0 0 0 0 0.5 0.5 you don't need separate pos and neg contrasts For mri_glmfit-sim, a threshold of 1.3 (p<.05) is way too
