Yes, it will work on both. If you use a table, then pass the table with
--table tablefile instead of --y

External Email - Use Caution
Good morning,
Thanks Doug for the answers. Quick naive question. The analyses I want
to perform are on volumetric data parcellated using aseg and not
surface data.
Does mri_glmfit work with the output of the asegstats2table or on
voxelwise FA maps ?
Many thanks
Rito

Hi All,
I have the following data –
I have 205 subjects - each subject was imaged at 3 timepoints
(baseline, followup 1 and followup 2)
The 205 subjects are split in two treatment arms with 100
subjects in the first one and 105 subjects in the second one.
For each timepoint, I have created FA maps in their native
diffusion space.
I have also extracted the mean FA maps for 187 ROIs using
mri_segstats.
For each timepoint, I have saved the results as a matrix (FA in
187 ROIs x 205 subjects) in a text file.
So I have three files for the three timepoints.
I have the age and cognitive score for each subject at each
timepoint. And their gender.
I want to answer the following questions –
1. Do the baseline FA correlate with the corresponding cognitive
score at baseline ?

1. I am interested in testing whether the FA changed
significantly across the different timepoints and does that
relate to the change in the cognitive score

time ?

Can you please suggest what programs in freesurfer will allow me
to test these questions on both voxelwise and ROI wise ?
