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
