WebSeurat can help you find markers that define clusters via differential expression. By default, it identifes positive and negative markers of a single cluster (specified in ident.1), compared to all other cells. FindAllMarkers automates this process for all clusters, but you can also test groups of clusters vs. each other, or against all cells. WebOct 12, 2024 · 1. I wrote my own Shared Nearest Neighbor (SNN) clustering algorithm, according to the original paper. Essentially, I get the nearest neighbors for each data point, precompute the distance matrix with Jaccard distance, and pass the distance matrix to DBSCAN. To accelerate the algorithm, I only compute the Jaccard distance between two … WebDec 22, 2016 · SNN assigns objects to a cluster, which share a large number of their nearest neighbors.
