rna velocity

scVelo is a scalable toolkit for RNA velocity analysis in single cells, based on Bergen et al. (Nature Biotech, 2020).

RNA velocity enables directed dynamic information retrieval by taking advantage of splicing kinetics. scVelo generalizes the concept of RNA velocity (La Manno et al., Nature, 2018) by relaxing assumptions previously made with a stochastic and dynamic model that solves the complete transcriptional dynamics. Therefore, it adapts the speed of RNA to very diverse specifications, such as non-stationary populations.

scVelo supports scanpy and hosts efficient implementations of all RNA velocity models.



ScVelo Key Applications
estimate RNA velocity to study cell dynamics.
identify putative driver genes and regulatory change regimes.
infer a latent time to reconstruct the temporal sequence of transcriptomic events.
estimate the transcription, splicing and degradation reaction rates.
use statistical tests, for example, to detect different kinetic regimes.
scVelo, for example, has recently been used to study the immune response in COVID-19 patients and the dynamic processes in human lung regeneration. Learn more in this list of application examples.
