NettetCluster cells using the Leiden algorithm [Traag18] , an improved version of the Louvain algorithm [Blondel08] . It has been proposed for single-cell analysis by [Levine15]. This requires having ran neighbors () or bbknn () first. Parameters: adata : AnnData The annotated data matrix. resolution : float (default: 1) Nettet1. jan. 2024 · This task, called community detection or graph-based clustering, is ubiquitous across fields and is especially important in biology, where the function of a biological macromolecule such as a protein is often mediated by its interacting partners within the network. However, noise in networks can complicate clustering. deji floyd mayweather date
