Dear Donna and David,

Thank you for the helpful comments and suggestions. I successfully
finished flattening of an individual human brain and its spherical
registration to the human PALS atlas, and the registration is perfect. Now
I want to start flattening of an individual monkey brain and its spherical
registration to the macaque F99UA1 atlas. Before starting this process, I
just wanted to make sure that I am using the correct (and the most
up-to-date) files. In particular, I would appreciate if you provide me
with the SumsDB links for the following files:

1) Macaque template cuts for flattening (border file and border color file).

2) Macaque landmarks for registration (border color file and border
projection file).

3) F99UA1 atlas for registration (.spec, .deform_map, and sphere.coord

4) The complete F99UA1 atlas containing various .coord files (and other
Caret files) for surface visualization.

and a brief question about flattening: where is the location of "temporal
and frontal cuts" on the macaque cortex, and how can I draw them? (i.e.
where are the recommended start and end points for these cuts?)
