You need to build a wrapper that creates all possible combinations of the
three sets of par files.
Then use this to build a design matrix for each one.
Then estimate the efficiency (eff) and VRF (vrf) for the contrasts of
interest.
M = C*inv(X'*X)*C';
eff = 1/trace(M);
vrf = 1/mean(diag(
Dear Bruce,
Thank you. I transferred via ftp, the entire Freesurfer subject folder
(Sub5.zip).
The most pronounced "miss" segmentation is around coordinate 169 158 91,
but it extends from about 168 155 85 up until 168 164 106.
Thank you very much for taking a look at it.
Best,

Hello freesurfer experts,
I am trying to extract an average percent signal change from a functional
roi label I created in tkmedit using fsaverage. I followed previously
discussed methods:
1) mri_label2vol --label --temp fsaverage/mri.2mm/orig.mgz
--regheader fsaverage/mri/orig.mgz --o
2) I ch
Hi Eric
I think if FREESURFER_HOME is set properly recon-all will create the
symlinks it needs so you won't have to do it yourself (including the
fsaverage one - I just checked).
cheers
Bruce

Thank you Bruce and MIke!
I was not really looking for something INSTEAD of manual inspection, but
for a measure of the quality of my dataset similarly to what is
reccomended for functional MRI (in that case a SNR below 100 can be
considered a criterion of exclusion).
What are the meaning of these
Dear FreeSurfer Experts,
while I'm doing my first FreeSurfer analysis with QDEC (cortical thickness in controls vs. patients) I'm having a problem with the coordinates QDEC puts out in the Terminal. I read some rather old posts about that but wondered if there has been some development since.
