Dear List,
Apologies if this is a simple question, but how can I define the BA 46 within
ROI: middle frontal gyrus plus middle (or superior) frontal
sulcus?--

Hi,
For a stimulus condition 'A' and a fixation condition, does the ces file
for the contrast 'A - fix' correspond to the % signal change for the
condition A?
Thanks,

Are the average subjects generated by different version of Freesurfer differ
greatly?
I obtained the cortical thickness,lGI using Freesurfer 4.0.3,
However, average subject can not be generated using Freesurfer 4.0.3 because
of error.Can I use the average subject generated using Freesurfer of
They should be exactly the same data, so it could just be a
human-factors perception problem. I'd guess that the tkmedit image is
larger than the probedicom image, so it will look worse. Try viewing it
from a few feet away:).

Hello.
I have a question in regards to Doug's suggestion. When I view the image
using mri_dicomprobe, the image is great. However when I convert the dicom
files into nifti to view and work with in tkmedit, the images I get in
tkmedit are very poor quality. I used:
mri_convert -i .dcm .nii

Mark, what context are you running it in? Ie, are you running it by
itself or was it called by something else. It looks like the subject's
surface and the overlay that you are smoothing have different number of
vertices.

Hello Freesurfers !
I have very basic question. I suceesfully completed autorecon first time and
now I want to extract the segmentated brain regions/ labels, as a ROI, so
that I can use them in diffusion(b0) space.
can any one suggest me related wiki page, where I could start for this and

Dear FreeSufer Experts,
I was running the recon-all autorecon-all -s bert step and I have got the
error message below. this is the first time I see this message although I have
analysed more than 7 MPRAGEs.
Any suggestions please?
Note: I usually call my subject as bert.
Thanks

Hi FS experts,
I am trying to display a large set of peaks on an inflated brain to
illustrate the spread of the peaks over a gyrus & sulcus, similar to
what might be done in a meta-analysis. Is there an easy way to do this?
I tried generating a binary mask in 3D (in MNI space) and then

Joost,
Try adjusting the overlay display in tksurfer: View->Configure->Overlay,
then select Linear Threshold, and try changing the Min and Max.

yes, you can certainly do multiple time points. Just do we one in the
same way.
A low # of topological defects is probably a good thing, but computing
CNR would be a better direct measure of sequence quality.

Dear FS experts
Thanks a lot for the beta version of recon-all -long. It works fine. Is it
possible to use more than two time points in the recon-all -long pipeline.
If yes, can I add the third and forth time point of each subject with
additional -i options (-i tp3.nii -i tp4.nii)?
If no, is there
