Re: [HCP-Users] Extracting Thalamus Brainordinates

Okay, but be aware that the volume registration isn't perfect even for subcortical structures. We go to some trouble to deal with the non-overlapping edges without mixing data across individually-identified subcortical structures when we put subcortical data into CIFTI. I don't know how bad the

Thanks Tim and Ely, This is helpful. Tim, I think I prefer your second suggestion (using the standard cifti MNINonLinear group definition). I need a one to one correspondence between every point in the thalamus across individuals and to a template thalamus. The reason (and perhaps I need to

It may be better to use the individual subject's "native space" definitions. The files in the T1w folder are in what we refer to as native volume space (it is actually rigidly-aligned MNI space, but rigid alignment preserves shape, so it can be used as if it were distortion-corrected scanner

Hi Claude, Are you using workbench viewer? If so, you should be able to identify particular thalamus or other subcortical MNI coordinates in the Volume tab (brainordinate subcortical coordinates = MNI coordinates). You can also split the thalamus structure out from subject¹s CIFTI file, if you
