scVelo: RNA velocity of single cell generalized through dynamical modeling.

scVelo is a method to describe the rate of gene expression change for an individual gene at a given time point based on the ratio of its spliced and unspliced messenger RNA (mRNA). It avoids errors in the velocity estimates by solving the full transcriptional dynamics of splicing kinetics using a likelihood-based dynamical model. This generalizes RNA velocity to systems with transient cell states, which are common in development and in response to perturbations.
