External Email - Use Caution Dear Freesurfer experts,
I'm running (FS 7.1.1) segmentThalamicNuclei.sh on T1 scan from recon-all. On a sample of about 100 subjects I've found an average volume of 250 mm^3 and 290 mm^3 for LGN-left and LGN-right, respectively. Consistent with literature, I would expect an LGN volume around the order of 100 mm^3. Do you have any suggestions to address this issue?
