It seems we can see cell types with the single cell ATAC-seq data. (See the figure below - data from the ongoing Kaggle challenge: https://www.kaggle.com/code/alexandervc/mmscel-atac-seq-eda-01-dimred-visualizations?scriptVersionId=105765396&cellId=17 )
What is the other biology we can see with scATAC-seq ? And vice versa - difficult to see ? Can we see cell cycle phases for example ? (Googling did not help me). Degree of "stemness" ?
PS What seems surprising for me that cell types seems to be seen more clearly via ATAC-seq data, rather than via scRNA-seq data. Is it always the case ?
