WebApr 11, 2024 · Protein-protein docking reveals the process and product in protein interactions. Typically, a protein docking works with a docking model sampling, and then an evaluation method is used to rank the near-native models out from a large pool of generated decoys. In practice, the evaluation stage is the bottleneck to perform accurate protein … WebMar 31, 2024 · The point cloud grid method generally consists of three steps. First, the depth camera captures point clouds containing depth information. Next, each point of the same depth is matched with a depth grid node; that is, each depth grid contains all points at the same depth. Finally, according to the coordinates of each layer in the generated grid ...
