Hi Mike,
sorry for the delay, I was unavailable for most of yesterday. There's
not a way to automatically do it, but it can be done. Eg, if you have
two groups (classes) and one continuous variable (eg, age), and you
want to test for an interaction between group and age, then you'd set
up
running freesurfer-v3.0
SUBJECTS_DIR=/home/gkirk/freesurfer-v3.0/freesurfer/subjects/sickle_cell
glm is at /home/gkirk/freesurfer-v3.0/freesurfer/subjects/sickle_cell
and contains
age.mat lh.sickle.glmdir mris_preproc.surface.lh.log
rh.sickle.thickness.10.mgh
FSGDstudy.txt lh.sickle.thicknes
