Dear Tuba,
There is something going badly wrong here. Could you describe your exact
list of steps from the moment you click on the Results button?
If you are getting the ROI data from the VOI button, why are you first
masking your results instead of specifying the mask at the VOI step?
Best regards,
Guillaume.
