Thanks Nick. Would coding the data by elements/label GroupGenderHandedness be equivalent to looking at group effect and then covarying for gender and handedness?
Thanks!

Vina,
Qdec still doesnt support more than four variables, but you can still do the analysis by manually creating the input files to mri_glmfit by following this tutorial:

Hello Freesurfer group, I have a couple of questions - I'm using FreeSurfer 4.0.3 to recon-all my data. I've started using Qdec and I realized that it won't accept more that 4 variables to be selected. I would like diagnosis to be my main variable and then age, gender, and scanner version as covariates.
Do you know if there is a different version of Qdec that would allow me to do that analysis and if it is a problem to use data processed with a different prior version with it?
Thanks, Vina
