Hello Natalia,
this is rather straightforwrd using functionality available within spm.
You could mask your t-map (or whatever) with your region of interest and
then use spm_vol and spm_read_vols to read the data into memory. You can
then use Matlab's max and find functions to find the location of the
maximum value, or search Mathworks file exchange for findn, one of my
favourites, which gives you voxel coordinates right away.
Hope this helps,
Marko
