[Freesurfer] flattenning question

2011-05-20 Thread Gabriel Go.Es.
Dear FreeSurfers I'm wondering about the flattenning options of FS I've saw that the "mris-flatten" command does the trick but, it asks for a patch, my questions are: can I flat any cortical region? and, how do I create a patch to mris_flatten? Thanks in advanced, Gabriel

Dear All, I am working with the volume-based stream in Freesurfer and I have a question about what is the difference between the volumes given for Cortical-white-matter and Cerebral-white-matter? How are the volumes calculated for both in Freesurfer? Is it the difference of including or not inc

Hi Gabriel you cut the patch out in tksurfer first, then call mris_flatten. For small patches such as occipital ones we typically use the -complete option these days which minimizes the complete distance distortion matrix. cheers Bruce On Fri, 20 May 2011, Gabriel Go.Es. wrote: > > Dear Free

Continuing the conversation, if I have a flattened patch like an occipital patch, and i manually draw a label on it and save it, can I then use mri_label2label to map it to other subjects ? Thx Ri - Original Message - From: "Bruce Fischl" To: "Gabriel Go.Es." Cc: "free surfer" Sent:

Which version of FreeSurfer are you using? In the more recent versions, they are the same. Cortical White Matter is all the white matter contained within the white surface minus the subcortical gray matter and ventricles, etc. On May 20, 2011, at 7:37 AM, "Righart, Ruthger Dr." wrote: > Dear

Hi Allison, Thank you very much for your help! I am using v5.0.0. Is the surface of the white-matter (from the surface-based stream) used here to calculate the volume in CorticalWhiteMatterVol and is this why I have sub-millimeter values here? This value is in fact different from the value that

Thank you bruce, Now I'm trying to flatten a part of the surface, now i'm wondering if it is possible to set an overlay to the flatten surface just as in the inflated by loading it on tksurfer. Bests, Gabriel > Date: Fri, 20 May 2011 08:26:40 -0400 > From: fis...@nmr.mgh.harvard.edu > To

sure. Just load a surface in tksurfer, then use file->load patch to load the flattened patch On Fri, 20 May 2011, Gabriel Go.Es. wrote: > > Thank you bruce, > Now I'm trying to flatten a part of the surface, now i'm wondering if it is > possible to set an overlay to the flatten surface just as i
