VeloSim is a simulation package that generates single-cell RNA Sequencing data for continuous cell developmental process. Given the cell developmental trajectory backbone, e.g. tree, cycle, cycle-tree, etc, VeloSim is able to simulate the whole dynamics of mRNA molecule generation, produces unspliced mRNA count matrix, spliced mRNA count matrix and RNA velocity at the same time. VeloSim can be easily used to benchmark trajectory inference and RNA velocity inference methods.

You can install VeloSim using following command:

devtools::install_github("PeterZZQ/VeloSim")
