Bottom line: Use pseudobulk + DESeq2 in simple and pseudobulk + DREAM in more complex settings.

RCS measures how large a cell niche (aka spatial domain aka spatial cluster) is compared to what would be normally expected.
This pushed me to completely rewrite the system for generating and plotting boundaries for cell niches.
The new system is now more efficient, consistent, and visually clear.

An alternative to tSNE & UMAP for more accurate data visualization:
Tree representations for distortion-free visualization and exploratory analysis of single-cell omics data.
The trees are constructed to accurately represent true distances between the objects in the high-dimensional space.
