Doug, Sorry for so many questions, but can I run the autorecon3 command with my previous recon-all -subjid (subject ID) -autorecon-pial or will the autorecon3 have to follow the previous command? Thanks, Cyrus -Original Message- From: freesurfer-boun...@nmr.mgh.harvard.edu [mailto:fr

Hi Doug, Thanks for the quickly reply. The new version of mri_segstats works fine. I noticed after running it though that all the volumes are slightly different than those reported by previous version. I think it might have something to do with the partial volume correction, as the results are

yes, this is a fix that will be in the next release. The new results are more accurate. doug On 08/22/2012 11:54 AM, Blazey, Tyler wrote: > Hi Doug, > > Thanks for the quickly reply. The new version of mri_segstats works fine. I > noticed after running it though that all the volumes are slightly

Hi Alex, there's no way to "erase" it in a way that you can recover the underlying signal. I'm surprised that such small things are causing the talairach to crash. If the writing is always the same value and that value does not appear in other parts of the image, you might be able to replace
