Hi Alireza,
Sorry for the delayed reply, but you happened to catch us at a workshop
on human consciousness; I normally don't work on Saturday, but I'm
headed to day 2 shortly.
A full reply would take more time than I have, but the short answer is
that I don't think Caret does quite what you want -- yet. I think there
is a spatial query under development in sumsdb, but it isn't quite ready
for prime time yet. That said, you might check out the foci tutorial here:
STEREOTAXIC_FOCI
http://sumsdb.wustl.edu/sums/directory.do?id=6617378
Just scan the PDF; you'll be able to tell if it's useful.
Another source to try is here:
http://brainmap.org/
While this isn't flat map related, you might still find it useful.
One could write a script/program that would find the closest node on the
SPM*/FLIRT/MRITOTAL PALS surface to any given MNI coordinate, and then
lookup the paint attributes associated with that node, but I don't know
of an existing utility that makes it easy.

Dear Caret experts,
I have mapped my functional data from SPM5 on flat brain using latest
version of Caret and now I would like to check some
specific activation(I expected to be among the activations which has
been mapped on flat brain) like [x,y,Z](MNI coordinate).one bothering
way would be click on each activation and see if the coordinate that
comes up in voxel(anatomy) section is the same.but first of all do the
[X,Y,Z] coordinate which is reported by voxel anatomy shows MNI
coordinate?second,is there a better way of entering MNI coordinate
and see the corresponding region to that? lets say entering[x,y,z]
(MNI coordinate)and see where is that coordinate on the flat brain?
Thanks,
Alireza
