Re: [Freesurfer] TRACULA GLM output question

[Douglas N. Greve]

The easiest thing is to set up contrasts to pull out the parameters you 
want. The next easiest (or maybe the easiest) is to look in the beta 
file. It will have a frame for each column in the design matrix. The 
value is the regression coefficient.

We’re working on a project where we ran 3 groups, 1 covariate, and ran 
a glm looking at white matter at cross-sections from TRACULA output, 
covarying for functional activation. We’re now wanting to plot out the 
interaction/slopes per group, but are having trouble locating the data 
that would allow that step.  Could anyone direct us?


Thank you!
