Thanks Doug, Nick and Marie for your great support!
With regards to what you wrote to Maartje about the total gray matter
volume I understand that the best way to measure it is using
mris_anatomical_stats -l ?h.cortex.label subject ?h
for every subject and every hemisphere. Maybe we should
Dear all,
I have got several questions about the analysis of my data. Maybe you
can help me out:
1) Regarding the different levels of smoothing (FWHM) in Qdec are there
already some 'standards' that one should usually stick to? My results
look better when I set the smoothing level to 15 or

Marie,
Are any special toolboxes required in Matlab to run the lgi code? Or
will plain matlab suffice?

6) I would like to have a look at the local gyrification index aswell
but still need to buy Matlab for it. Do I also need some extra toolboxes
to run the lgi calculation - or do
Christian,
as long as all your subjects were recon-all'd using the same version
(4.0.2), then you can use qdec and mri_glmfit from 4.05 or 4.10.

4) All of recon-all has been run with Freesurfer 4.02 for all subjects -
is it OK to use Freesurfer 4.05 or 4.10 for the analysis?
Best
Marie,
