[Freesurfer] prefrontal cortex values
Hello, I require values (total volume) for the prefrontal cortex. I see labels for "G_frontal_middle" and "G_frontal_superior" in the lh.aparc.annot files - are these correct to use? If so, could I add up the values for these to get one total volume for the PFC?

Re: [Freesurfer] Freesurfer to DTI space
I'm not sure if you can use that or not. The best thing is to use bbregister to align the low-b to the anatomical, then use the resulting matrix as input to mri_label2vol. doug On Tue, 8 Jun 2010, Tina Jeon wrote: > Hello all, > > I am using surface tracking in FSL to align my freesurfer surfaces to my > diffusion data.

[Freesurfer] sorry for repeating, PFC question

[Freesurfer] Registration of talairach and original space?
Hi all, We have used mrivol2surf with the output of bbregister to transform an individual subject's fmri data into the coordinates of the anatomical used to generate that subject's surface. We are happy with the accuracy of this registration. However, we are stuck because as far as we know bbregister only works in one direction, fmri to anatomical. We have a region of interest defined as a sphere around a coordinate in Talairach space. What we need to do is to translate that region of interest into the space of an individual subject's fmri data. How can Freesurfer do this? Any suggestions would be greatly appreciated!!

Re: [Freesurfer] Snowy background for T1 images
Hi Dave, 001.mgz in /mri/orig/ looks okay but 002.mgz looks strange, which I think is the reason for what you are seeing in T1.mgz. Did you collect 2 runs for structurals. Can you point me to the dicom files for this dataset or the scan log. Sita.

Re: [Freesurfer] Registration of talairach and original space?
We have another question that is very related, so I will ask that at the same time: We have a region of interest defined on an individual subject's surface. How can Freesurfer translate that ROI into the coordinates of the original fmri data? It's clear to us how to get from fmri to the surface, but not the other way around.

[Freesurfer] retinotopy: MGH vs UCSD
Hi all, I would ask you about freesurfer and retinotopy. I'm going to begin the analysis of some retinotopic data. I would ask if you know if the retinotopic analysis made by MGH freesurfer is qualitatively comparable to, or it's good as, that made by USCD freesurfer (old freesurfer). Thank you kindly in advance.
