Hello FreeSurfer Developers,

I’ve segmented thalamic nuclei via thalamic nuclei atlas (https://secure-web.cisco.com/1WjR2s5Zpo0C0UoA2TqjDmB6EwtzK0RI_lg2slhweQFKPQn...) and gained volume result of 25 subregions of each thalamus, but some subregions (eg. Right Pt) cannot be shown by load ThalamicNuclei.v13.T1.mgz in freeview. I'm attempting to use this thalamic nuclei atlas for functional ROIs analysis, using other softwares (eg.SPM). Could you provide .nii file of this atlas? Or can you help me show this missed thalamic subregions? Or how can I transform the file of thalamic nuclei atlas in FreeSurfer pipeline to .nii file.

I've searched the list and no similar errors have been reported. Does anyone have any thoughts on how to trouble-shoot this one? 1) FreeSurfer version: freesurfer-Linux-ubuntu20_x86_64-7.3.2 2) Platform: Ubuntu Release 20.04.6 (focal)
