Hello, I am looking at texture within a kidney, but removing all cysts to look only at healthy tissue. I was wondering how this would affect GLCM and other features, because there will now be pixels of 0 value within the ROI. I put this final image into pyradiomics to compute features, but I do not want to include the 0th pixels in the computation. ![20000599Left Kidney919](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/a/d/ad6a9a561e341c7f24c28fc4e1b676741e0ee8fe.png) Thank you! ---
