scVelo - RNA velocity generalized through dynamical modeling

https://user-images.githubusercontent.com/31883718/67709134-a0989480-f9bd-11e9-8ae6-f6391f5d95a0.png

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 [Manno et al., 2018]. scVelo collects different methods for inferring RNA velocity using an expectation-maximization framework [Bergen et al., 2020], deep generative modeling [Gayoso et al., 2023], or metabolically labeled transcripts [Weiler et al., 2023].

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.
