Hi Fernanda,

Design is fine. Just follow the randomise manual. Since your design doesn't have an intercept, make sure you use the option -D, to mean-center both data and design.

All the best,

Anderson

Dear FSL's expert, 

I would like to know about the correlation value (-r).
We did an analysis with TBSS correlating FA with a score (numerical variables). The design matrix was done in FSL itself in GLM setup with 2 contrasts: postive (+1) and negative (-1) as you can see in the image below. (the GLM bellow was with AGE as a variable of no interest).

Please, can anyone help me?

Thank you, 

Fernanda
