Hi - 

I'm wondering where I can find more information about the jhu189.nii.gz template, as well as the ch2bet.  Mostly, which MNI template are these two images normalized to? They seem to fit relatively similarly to the MNI152Lin6Asym, but just a tad off.

Thanks!

The ch2bet is based on a single individual and is described here:

While I am happy that my classic MRIcro and MRIcron tools have proved mature and popular, please understand that my development efforts focus on modern graphics hardware  resulting in MRIcroGL and NiiVue. Personally, I prefer the mni152 and spm152 templates provided with MRIcroGL. These are based on the 2009 atlases with MNI size (larger than average) and SPM size (average) to match the most popular normalization atlases:
