Re: [Freesurfer] a problema

if you visualize them on fsaverage it has parcellations (e.g. lh and rh aparc.annot and a2005saparc.annot) in the label dir you can load that will display this info cheers, Bruce On Wed, 21 May 2008, yczhang wrote: Using lgi or thickness,how could I know the anatomical correspondence for a

[Freesurfer] retinatopy question

Hello, I have a basic question regarding retinatopy analysis. In the paradigm files we specify whether the run was mapping eccentricity or polar angle stimulus, and we specify the number of cycles in mkanalysis. Don't we need to be more specific about the stimulus, i.e. how many wedges trace one cy

Re: [Freesurfer] segmentation problem

Hi Rachel, looks like the superior gm is very dark, so some control points in the superior wm should help. That said, this is much worse than we usually see. Let us know how it goes. cheers, Bruce On Tue, 20 May 2008, Dick, Rachel wrote: Hello, I'm having some issues with the cortex as

[Freesurfer] WM parcellation regions

Hi everyone, Our group is interested to know whether there is a way to view the WM parcellation regions as you would gray matter. My understanding is that the viewer options are for white matter hemisphere totals, as in it's either left or right. Thanks again! Marlisa Marlisa Isom Research Coord

[Freesurfer] BA labels

Hi, I had a question regarding the labels listed in FreesurferColorsLUT.txt. Does any of the data Freesurfer outputs contain Labels 400-409 (corresponding to various Brodmann's Areas)? I've never seen those labels used in the publicly-released version, but wanted to verify since a coworker was spec

Re: [Freesurfer] BA labels

Hi Aaron, if you look on the wiki there's an online preprint of a forthcoming Cerebral Cortex paper on this. We're happy to distribute the labels and were going to include them in the next release I think in any case. cheers, Bruce On Wed, 21 May 2008, Goldman, Aaron (NIH/NIMH) [C] wrote:
