RE: [Freesurfer] major lobes - frontal, parietal occipital and temporal

Hi Bruce, I am using freesurfer to generate masks for fmri data from a breath hold task. As you are probably well aware, this task activates much of the gray matter. I have been content to consider all gray matter as one large ROI but one of my colleagues on the project (Danny Mathalon) has sug

Hi Lee, what is your goal? Are you just trying to measure lobar volume? Bruce On Sat, 14 Apr 2007 [EMAIL PROTECTED] wrote: Burce and Rahul, thanks so much for your help. So I am a little new to freesurfer. I have been using lh.ribbon and rh.ribbon as neocortical masks and aseg.mgz for sub

RE: [Freesurfer] major lobes - frontal, parietal occipital and temporal

The occipital lobe also includes the pericalcarine region (i think you just forgot to include that one in your list). On Sat, 2007-04-14 at 17:33 -0400, [EMAIL PROTECTED] wrote: > Hi Lee, > > Bruce is correct in that some ROIs cross two or more lobar boundaries > (i.e. fusiform) while others (i.

Burce and Rahul, thanks so much for your help. So I am a little new to freesurfer. I have been using lh.ribbon and rh.ribbon as neocortical masks and aseg.mgz for subcortical gray structures, with labels from FreeSurferColorLUT.txt. What I want to do now is to further subdivide the *h.ribbon mas

RE: [Freesurfer] major lobes - frontal, parietal occipital and temporal

Hi Lee, Bruce is correct in that some ROIs cross two or more lobar boundaries (i.e. fusiform) while others (i.e. cingulate subdivisions) can be considered separately or can be included to follow the 4 lobes. To the best of my ability, if you are using the *h.aparc.annot, you can add up the individ

Hi Bruce, Are you saying that you don't think I even could build these lobar groups using the existing codes in the LUT.txt file? Lee -Original Message- From: Bruce Fischl [mailto:[EMAIL PROTECTED] Sent: Saturday, April 14, 2007 2:21 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subjec

RE: [Freesurfer] major lobes - frontal, parietal occipital and temporal

I don't think so, but Rahul (ccd) would know for sure. I think a bunch of them cross lobar boundaries On Sat, 14 Apr 2007, Lee Friedman wrote: Hi Bruce, Are you saying that you don't think I even could build these lobar groups using the existing codes in the LUT.txt file? Lee -Origina

Re: [Freesurfer] major lobes - frontal, parietal occipital and temporal

Hi Lee, sorry, not really - we've never done a lobar parcellation, and I don't think the existing units break down that way. Bruce On Sat, 14 Apr 2007 [EMAIL PROTECTED] wrote: I know that I could go thru the FreeSurferColorLUT.txt file to get codes for different cortical structures. Is the

[Freesurfer] major lobes - frontal, parietal occipital and temporal

I know that I could go thru the FreeSurferColorLUT.txt file to get codes for different cortical structures. Is there an easier way to get the major lobes: frontal, parietal occipital and temporal. Lee ___ Freesurfer mailing list [EMAIL PROTECTED] https:
