scCODA is a Bayesian model for compositional single-cell data analysis

Compositional changes of cell types are main drivers of biological processes. Their detection through single-cell experiments is difficult due to the compositionality of the data and low sample sizes. We introduce scCODA (https://github.com/theislab/scOODA), a Bayesian model addressing these issues enabling the study of complex cell type effects in disease, and other stimuli. scCODA demonstrated excellent detection performance, while reliably controlling for false discoveries, and identified experimentally verified cell type changes that were missed in original analyses.

Automated summary

scCODA is a Bayesian model that effectively detects cell type changes, addressing the difficulties in single-cell experiments. It demonstrates excellent performance, reliably controls false discoveries, and identifies experimentally verified cell type changes missed in original analyses.
