Hi Dorsa
I don't see any holes in the thalamus in your aseg, nor separated pieces. What voxel coords do you mean? Remember to look at the data in other orientations. Things that look like islands in one view may be peninsulas in anothers
cheers

I mean the holes in the thalamus and also some parts that are labeled as thalamus but not attached to the rest of thalamus volume.

Yes it is taken at 3T. I have asked our team to provide these information about the MRIs and will let you know when I hear back. I also wanted to ask if you know a good way to refine the thalamus and fill out the missing parts within the volume?
