Hello Freesurfer experts.

I am trying to run a QDEC analysis on some MRI data I have. I want to see if thickness is correlated with language scores I have for each subject, while accounting for differences in age, and gender.

I would like to select the gender as a fixed variable, and both the age and language scores as continuous variables, however the QDEC GUI will not allow me to select more than one continuous variable at a time (from what I've read on the website/mailing list I should be able to select up to two.

Any idea of what might be wrong here, and how I can fix it.

Thanks So much,

Matthew Walton
