Hi all :

     I'm performing general linear model (GLM) analysis in the surface,the attachments above are FSGD file  and contrast files(the last three attachments).i wonder if my contrast files are correct.

    the attachment named diff-C-H-thickness.txt is about difference between C and H and the last two are about difference between C and p and difference between P and H,Here,C  H and P represent three groups

 

   Any suggestions appreciated
