Portal Dosimetry Example Script: CountGammaPixels

Jan 18 at 2:37 PM
Does anyone know why the CountGammaPixels.cs example script in Portal Dosimetry returns 0 for ROI Count and 0 for Pixles in ROI Gamma >1 when the ROI = CIAO? Is the CIAO not in the ROIMask? If not, where is it? Thanks for any help.
