External Email - Use Caution        

Hi Douglas,

I just try your suggestion. It gives me information like the following. What does the design matrix stands for? Thanks.

ERROR: design matrix is not orthogonal, cannot be used with permutation.
If this something you really want to do, run with --perm-force

My guess is that something is going wrong with the backgrounding. Try 
running it without the --bg option. You can run it with a few (eg, 100) 
iterations just to see if it finishes.

Dear Freesurfer Experts,

I am running the multiple comparison (permutation) on a MAC with the 
following code. It has taken 8 hours and has not finished yet. It 
gives me Poll jobs information without end. According to tutorial 
information, it will only take around 20 minutes. Do you know what 
should I do if I want to use this perm multiple comparison? I have 
attached my MAC system information and the Poll jobs information. 
Thanks a lot!

Best wishes,
Ting
