My apologies as I misstated some of the data in my first email, The voxel sizes are relatively similar, (two of the acquisitions are 1mm vs one with 0.9mm). Whereas the FOV is different between the scans being 256x256x176 on one acquisition, 224x256x176 on the second and 240x240x180 on the thir

Dear Freesurfer Team, We would like to have a Q/A measure (or two) that would give us indication of how well your software worked on each of our data sets. Obviously some image sets will be noisier than others for a variety of reasons. Could you point us towards what options we may have for e

Dear Freesurfer experts, I am attempting to use QAtools to retrieve QA measures for my subjects. I can obtain WM SNR/avg/sd, but it appears the structural segmentation table is from a previous version of freesurfer (as the file order is different) and doesn't appear to work with my subjects pr
