Re: [Freesurfer] FA (DTI) statistical analysis: 3 covariates

Hi Jay, it is an extension of the one group two covariate http://surfer.nmr.mgh.harvard.edu/fswiki/Fsgdf1G2V (which I just created just for you:). doug

Dear Freesurfer experts, We are trying to run a statistical analysis for FA in 5 ROIs. We have one group of subjects and our goal is to run regression analysis to find a relation between one behavioral test (episodic memory test) and FA. We are planning to set

• the accuracy on episodic memory test as the dependent variable.
• age, sex and MMSE (range 21-30) as covariates
• FA in each ROI is the predictor

We couldn't find an example of 3 covariates on the tutorial website, could you kindly let us know how to run glm analysis for 3 covariates? Thank you Jay Morozov
