[caret-users] MNI coordinate

[Donna Dierker]

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.
