WebbPseudotime analysis is, perhaps, one of the major analysis that can be carried out in SC data. It aims to depict a trajectory, a sort of order in which cells transition from A to B. What defines this process, and the starting and end point is heavily driven by the research question, the nature of the data and prior knowledge. Webb1 apr. 2024 · Trying to analyse cells every 10 seconds can be pretty tricky, so ‘pseudotime’ analysis takes a single sample and assumes that those cells are all on slightly different points along a path of differentiation. Some cells might be slightly more mature and others slightly less, all captured at the same ‘time’.
