Hi Freesurfers, Some associates of mine are working on a pipeline that generates cortical parcellations and we are looking to compare its measurements to some measurements generated by the freesurfer pipeline. However, our pipeline parcellates broader regions which include several labels generate

2008-07-10 Thread Ryan Scotton
Hi all, I am fairly new to FreeSurfer and I've just finished initial runs on about 140 MRI images. Now, my job is to go through and do a little QC that helps ensure that the cortical thickness values are as accurate as possible. Now, I have a few questions: 1. Am I right in assuming that cort
