Slicer version:4.10.1  
Hi 3D Slicer experts and all  
I exported RT Dose(Dimension:62x46x88) from TPS and I converted it to a volume (Dimension: 256x256x89) using Resample Scalar Volume Module. I want to calculate DVH for this volume with Dose Volume Histogram module.But I can’t enter this volume as a Dose volume in input section. How can I calculate DVH for this volume?can you help me?  
Thanks a lot

You can either

1. Uncheck “Show dose volumes only”, but then it will be an “Intensity volume histogram” (only affects plot title and similar), or
2. Convert regular volume into a dose volume. See slides 17 and 18 in the latest [tutorial](https://www.slicer.org/wiki/Documentation/Nightly/Extensions/SlicerRT#Tutorials)
