Web“Trajectory inference or pseudotemporal ordering is a computational technique used in single-cell transcriptomics to determine the pattern of a dynamic process experienced by cells and then arrange cells based on their progression through the process.” Trajectory inference remains one of central interests in single-cell transcriptomics studies. WebPseudotime 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. cristina tajani biografiaWebJul 12, 2024 · While many computational methods have been developed to infer the pseudo-temporal trajectories of cells within a biological sample, methods that compare pseudo … cristina sucu kiddo
