Hi,

I would like to run a group analysis on 4 groups (patientM, patientF, controlM, controlF) with 3 covariates (age, cogscore1, cogscore2).

I am running with dods - so I would have 16 total regressors. How would I create contrast matrices for this?

I have this so far:

0.5 0.5 -0.5 -0.5 0 0 0 0 0 0 0 0 0 0 0 0

0 0 0 0 0 0 0 0 0.5 0.5 -0.5 -0.5 0 0 0 0

0 0 0 0 0 0 0 0 0 0 0 0 0.5 0.5 -0.5 -0.5

Secondly, I created lh.train.thickness.10B.mgh since the initial run was not qcached. How can I check if there is an error with this file?

Thanks in advance.
