scVelo - RNA velocity generalized through dynamical modeling

scVelo is a scalable toolkit for RNA velocity analysis in single cells; RNA velocity enables the recovery of directed dynamic information by leveraging splicing kinetics ¹. scVelo collects different methods for inferring RNA velocity using an expectation-maximization framework ², deep generative modeling ³, or metabolically labeled transcripts⁴.

scVelo's key applications

• estimate RNA velocity to study cellular dynamics.
• identify putative driver genes and regimes of regulatory changes.
• infer a latent time to reconstruct the temporal sequence of transcriptomic events.
• estimate reaction rates of transcription, splicing and degradation.
• use statistical tests, e.g., to detect different kinetics regimes.
