The thalamic nuclei segmentation produces 2 mgz files. One has the FS suffix and other does not. Is the latter without the FS in the native space? If I import and view in freeview, they look same. I want it in native space so I can do some Dice calculations.
My manual segmentations are on a different data set very close to but not necessarily perfectly aligned to the T1 data set used in recon-all. I can use the mri_conver -rl 'reslice like' option but it does not do any registrations does it? It just reslices it in the orientation of the file argument to -rl right. I assume have to manually affine register and propagate the warps if they are not aligned?
Thanks, manoj
