Recreating Figure 4C from the original publication on the tutorial data

[aaronkwong]

Hi,

I am running Tangram and have been trying to reproduce a quality control plot similar to 4c in the original publication which shows the distribution of correlation coefficients in the genes used for training and testing.

I have tried to create this QC plot taking the results generated from the tutorial (unconstrained mapping), but from my plots am seeing that while the training genes have a high correlation coefficient, those of the testing are all around close to zero. I was expecting this plot to look more similar to the one in the publication.

Would you be able to share the code used to generate quality control figure 4c after mapping cells?

Thanks,
Aaron
