Hello I would need to use a brain region from the DD_Desai_MPM atlas .
It's indicated on the website that is uses the TT_N27 template space

but I'm wondering what the difference between the TT_N27 and the TT_152_2009c
cause the 2009c looks way better for resolution and I would like to use that instead.
Any link I can find about that?
