Briefly, RNA velocity analysis allows us to infer Normalize and cluster cells using pagoda2. However, I'm quite confused about the fact that they only applied normalization (via SCTransform function) on the "spliced" assay but not on the The main parameters are set up by sigma (which limits the range of how far a cell can jump in terms of distance) and n (how many nearest neighbors are being considered for jumps).
