Dear FreeSurfer experts,
I am attempting to disentangle the effects of different features of
pharmacological treatment on cortical thickness.
I am running glmfit from the commandline, with multiple covariates (a.o.
Z_Age, Z_TreatmentDuration and Z_StartAge) in the fsgd-file. These
Dear all,
I am planning to create a local cortical thickness normal template in
order to test single patients against it.
For that purpose I was planning to use 50-100 MPRAGE scans of healthy
subjects (balanced for age range and sex).
My question is, if I should worry about the scanner where
Hi Markus
there is no way to know until you try it. There are many possible sources
of variance depending on e.g. how uniformly they are calibrated, but you
have to try and see.
cheers

Thank you Bruce!
Good! So, at least it doesn't seem an impossible thing to achieve!!

Hi All,
Would please let me know about the origin of volume in the measures menu of
Qdec, so I can interpret the results from group comparisons. Is it Gray
Matter volume?

Hi Doug,
Thanks for your reply. Just to be clear, I need to ask some trivial
questions:
1) I need to do that subtraction in the fsgd file right? (In which case
there will be negative numbers as well)
Correct.
2) I ran the analysis
But what is in rh.ttest.thickness.10.mgh? Is it a stack of all your
subjects (the file you passed with --y to mri_glmfit)? If so, then add
-t rh.ttest.thickness.10.mgh to your tksurfer command line. Ruopeng
just added something to freeview to do it, but you'd have to get a new
version

Use mri_surf2vol to do this. Soemthing like
mri_surf2vol --surfval rh.36...mgh --hemi rh --fillribbon --subject
fsaverage --template $SUBJECTS_DIR/fsaverage/mri/orig --o yourvolume.nii

Hi Bruce,
Thanks Bruce.
I knew that code, but I have no
It is just a standard multiple regression analysis where all regressors
are fit simultaneously. One weight does not include that of another weight.

Hi everybody,
I would like to ask a question about trac-preproc, because I'm new to
Tracula and I'm studying how the entire trac-all process works. I want to
know which is the specific structural image (I mean the name of the file)
that is registered to the dwi volume during trac-preproc, and at
Hi Francesco - If this registration is done with bbregister, which is the
default option in tracula, then it uses the lh.white and rh.white surfaces
from the freesrufer reconstruction of the structural. The low-b diffusion
images are aligned to those surfaces by optimizing the contrast of the

Hi doug,
Thanks doug.
I have 2 new questions:
1,What you told me is generate a hemisphere. So there is only one hemisphere I
can see in the AFNI?
2,After typing this code:
