External Email - Use Caution Dear FS experts, I am trying to run the cluster-wise correction by using permutation based multiple comparison. For this, as you would know, we use: mri_glmfit-sim In attempt to this, I tried running different options mri_glmfit --y lh.thickness.AT.1

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

External Email - Use Caution Dear FS experts, I am looking at the relationship between the cortical thickness and a behaviour measure, while controlling for the effects of age and gender. In this analysis, I am using CT_AT.fsgd, contrast_pos.txt and a contrast_neg.txt. GroupDescr
