Hi,
I am using freesurfer 5.1.0 and qdec 1.4. I'm interested in looking at between group differences in thickness in relation to two other continuous measures whilst controlling for ICV. However, qdec doesn't seem to let me select more that one continuous variable even though I only have group selected (discrete) and ICV (nuisance) as additional variables (i.e. a total of three selected) - it's my understanding that qdec allows up to 4 variables, is there a method to selecting multiple continuous variables that I am missing (e.g. hold down shift and select)?
Thanks!
Laura.
