recon-all -all will take approximately 30 hours. It depends on the quality of your data and how many errors need to be fixed. Allison -- On Wed, 29 Apr 2009, Elina Pitri wrote: Hello Freesurfer Creators, I am wondering how much time should Volume and Surface processing (using recon-all comm

Hi Elina, You could have a look at http://surfer.nmr.mgh.harvard.edu/fswiki/recon-all#Step-wiseDirectives-1 and http://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllDevTable to identify the needed time of each process. But I have to mention, that the timeline is not perfectly accurate and can vary

[Freesurfer] longitudinal processing

FreeSurfers, I am using the longitudinal processing stream to look at change in the lateral ventricles at several timepoints. As a control measure, we are running two consecutive baseline images in the scanner. These images were done back-to-back, exactly the same, and the subject did not ge

[Freesurfer] corpus callosum segmentation

The Freesurfer 4.3 segments the cc into 5 parts. But the wmparc.mgz has both 5 parts along with ctx-?h-corpuscallosum/ wm-?h-corpuscallosum. I think they should not co-exist. Maybe I¹m wrong. Wayne ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.e

Hi Dana, we have uncovered a problem with the longitudinal stream that may account for this. We're hoping to have a fix in the near term. cheers, Bruce On Wed, 29 Apr 2009, Dana W. Moore wrote: FreeSurfers, I am using the longitudinal processing stream to look at change in the lateral v

you're probably right. We used to segement the cc on the surface, but this wasn't nearly as accurate as in the volume, which replaced it. cheers Bruce On Wed, 29 Apr 2009, Wayne Su wrote: The Freesurfer 4.3 segments the cc into 5 parts. But the wmparc.mgz has both 5 parts along with ctx-?h-c

Thank you Bruce, So, if I want to report the volume of the Corpus Callosum, I should add up the volumes of CC_Posterior, CC_Mid_Posterior, CC_Central, CC_Mid_Anterior, CC_Anterior only. The ctx-?h-corpuscalosum/wm-?h-corpuscallosum is just useless and better to remove them from wmparc.mgz since th
