Focal Statistics - annulus inner radius to exclude processing cel

Discussion created by DennisJongsomjit on Jan 30, 2012
Sort of a simple question that I can't find a clear answer to online.  Does anyone know if I can run focal statistics using the Annulus option to get a neighborhood statistic that excludes only the processing cell itself but includes all other cells in the specified neighborhood.  My guess would be that I could set the inner radius to be half the distance of a cell to effectively exclude the processing cell. But this is unclear in the help files.
