I think it is CM.C = [0 1 0 0] if you want to test if the slope is
significantly different from 0. I also would say that for a dataset with only
two time points the results of lme will not probably be very different from
what you already got from mri_glmfit. lme is designed for more complex

Hi Vivian
The error you are getting means that
the number of elements of your contrast vector is not the same as the
number of columns of your design matrix. I think you're trying to
apply the contrast matrix shown in the wiki page example to the sample
dataset that we distribute with lme. Tha
Dear FreeSurfer experts,
thanks a lot for your solution.
It works fine.
I have some further questions to polynomial fitting with qdec, to prevent
misunderstandings from my point of view.
Only to be sure:
1) Linear effects of age: age as continuus factor.
2) Quadratic effects of age: age (q
Dear FS-Experts
We examined longitudinal t1-based data and used the -long pipeline and
mri_glmfit for testing time effects.
Now for a more powerful statistical analysis we're trying to set up LME for our
data but we struggle while adapting from the tutorials cmd's.
##Problem:
We currently st
Dear Freesurfer developers,
the "Configure Overlay Display" dialog is clipped on low resolution monitors
