Hi Ben if you upload the datasets we will take a look. I imagine this is due to dielectric resonance effects. What sequence did you use? Bruce On Tue, 6 Oct 2015, Benjamin Peterson wrote: > We have three 7T scans of the same person done on separate days. After > running all three T1 images usi

[Freesurfer] 7T thalamic segmentation inconsistencies.
