tumor only scRNA/scATAC data

[weihong1991]

I appreciate the authors' effort in developing and maintaining such a robust and user-friendly tool.
I am currently analyzing a PDX scRNA/scATAC multiomics dataset that lacks normal human cells and contains only a few normal mouse cells (fewer than 10). I have two questions:

1. Is it possible to use a separate dataset from corresponding normal tissue (from a different patient) as a normal reference?
2. Can SCEVAN also handle scATAC data?
   Thanks
