Bioc currentVeloViz: RNA-velocity informed 2D embeddings for visualizing cell state trajectories
Release Lineage
Entered 3.14 · Oct 27, 2021
Current · Requires R 4.6
Description
VeloViz uses each cell’s current observed and predicted future transcriptional states inferred from RNA velocity analysis to build a nearest neighbor graph between cells in the population. Edges are then pruned based on a cosine correlation threshold and/or a distance threshold and the resulting graph is visualized using a force-directed graph layout algorithm. VeloViz can help ensure that relationships between cell states are reflected in the 2D embedding, allowing for more reliable representation of underlying cellular trajectories.
