[Freesurfer] Automatic Subcortical Segmentation Editing?

2015-08-26 Thread Jennifer Eastman
Hello All, I am hoping to make some edits to subcortical segmentations, and while I have found instructions for manual edits, there are also stern warnings to avoid these if possible and pursue automated avenues. I cannot, however, seem to find clear instructions on how to automatically edit t

Hi All, I just wanted to bump this question back up.I am interested in comparing sub-cortical volumes across subjects in my data set. I am wondering if using the CVS registration step is useful in improving the accuracy of the sub-cortical volume measurements independently. I will not be examini
