Findclusters harmony
WebThe first step is to construct a K-nearest neighbor (KNN) graph based on the euclidean distance in PCA space. Image source: Analysis of Single cell RNA-seq data. Edges are drawn between cells with similar features expression patterns. Edge weights are refined between any two cells based on shared overlap in their local neighborhoods. WebThe FindClusters() function allows us to enter a series of resolutions and will calculate the “granularity” of the clustering. This is very helpful for testing which resolution works for …
