Hi Rick, in the future please post to the list and not to us personally.
Thanks! When you did the volume-based analysis, it should have masked
out anything anything that was not subcortical. Did it not? If not, then
when you run mri_glmfit you can add --mask
Hi Doug,
thank you very much for your answer!

OK, so basically do 2-stage modeling
Thanks Doug.
Any suggestions for a more appropriate design?
I guess this is a common situation where two or more parameters only
apply to one group (in this case patients) and are zero or constant in
the other.

Hello Freesurfers,
I am trying to run QDEC for a longitudinal analysis.
I've run the command "long_qdec_table --qdec ./qdec/long.qdec.table.dat --cross --out ./qdec/cross.qdec.table.dat" to adjust my qdec table to the right format for QDEC (with only one line / subject).

Hi Amy,
Good point. You can first use mri_vol2vol to upsample to 1mm:
mri_vol2vol --mov yourROIs.nii --targ
$FSLDIR/data/standard/MNI152_T1_1mm_brain.nii.gz --regheader --o
yourROIs_1mm.nii --interp nearest
then
mri_vol2surf --mov yourROIs_1mm.nii --mni152reg --hemi rh --surf white

Dear Freesurfers,
I am trying to display the regional regresssion coefficent for age in qdec.
However the colorbar still gives me the traditional 0, 1.3 etc

only regions that have more than say 0.3 correlation with age -

Yes I directly used the regheader option because in the steps before I
already registered ASL maps on anatomical T1.
The brain.fsaverage.lh.mgh come from the projection of the T1 brain mask
(dilated by 1) on the fsaverage.

Hi Amy,
Have you tried the --mni152reg flag instead of --reg
/usr/local/freesurfer/subjects/fsaverage/mri.2mm/reg.2mm.dat. Is the

p.s. Can you please reply all to the freesurfer list?

What do you mean that no surfaces were generated? There are two things
you have to do. One is to create the template. The second is to apply

You can use $SUBJECTS_DIR/fsaverage/mri/aparc+aseg.mgz (already in the

Hi Chris, the error was very unpredicatable. If you want to see whether

Can you use mri_surfcluster to do this? It can output a binary mask,
annotation, or label. You just need to give it the input and a
threshold. If you just want constrain it to a given label, then you'll
need to create a mask.

You would do the long analysis using a random effects analysis. For each

then follow the procedures from the archive email you reference.
