Hi Marie, But division by 5 would give the average area of the 5 mid slices. Maybe that is even more meaningful (reliable) than just a single slice. Best, Martin On 04/14/2013 09:05 AM, Bruce Fischl wrote: Hi Marie, no, that won't account for variability across slices in the l/r direction.

Hi Marie, no, that won't account for variability across slices in the l/r direction. Try rerunning mri_cc with -t 0 (thickness) and see if it generates a cc in just the midsagittal plane cheers Bruce On Sun, 14 Apr 2013, Marie Schaer wrote: Hi Bruce, Thanks for your response. Then I

Hi Marie It is mm^3 of I believe a 5 mm thick cc. We don't measure the thickness by default Cheers Bruce On Apr 13, 2013, at 2:18 AM, Marie Schaer marie.sch...@unige.ch wrote: Hi Bruce, Thanks for your response. My question was indeed: what is the unit of the CC_* output in the

Hi Bruce, Thanks for your response. Then I assume that I can divide these values by 5 and present them as area of the CC on the midline section, right? Have a nice week-end, Marie On Apr 13, 2013, at 5:18 AM, Bruce Fischl fis...@nmr.mgh.harvard.edumailto:fis...@nmr.mgh.harvard.edu wrote:

Hi all, I have a quick question related to the corpus callosum segmentation: I read in previous posts that the reference explaining more about the CC subdivision in 5 segments was the one by Rosas et al, Neuroimage 2010. But in this publication, you show thickness of the corpus callosum as
