Dear Pamela,
you will find the information in the xSPM struct after you pressed the
'Results' button and selected the appropriate contrast. Specifically,
size(xSPM.XYZmm,2) will give you the number of supra-threshold voxels
and xSPM.XYZmm will list the world space (mm) coordinates of them. See
the comments in spm_getSPM.m for an explanation of the other fields in
the xSPM struct.
Cheers,
Jan
