I also did a p-value ranking comparison between the xpore-dataprep on GoekeLab/xpore and the xpore-dataprep on yuukiiwa/xpore, and the two versions of the datapreps generated the same xpore-diffmod results with the demo-testdataset.

I have also crosschecked the xpore-diffmod results with and without transcript versions with the demo test-dataset, which show the same results.
