Webprefix. A character string to be added before each cluster identity. For example, if "Cluster" then cluster results will be "Cluster1", "Cluster2" etc. ArchRProj. An ArchRProject object containing the dimensionality reduction matrix passed by reducedDims. This argument can also be supplied as input. verbose. WebDescription. Identify clusters of cells by a shared nearest neighbor (SNN) modularity optimization based clustering algorithm. First calculate k-nearest neighbors and construct …

WebAssuming you have an informative selection of variable genes from which you have constructed a number of useful PCs, I'd run a number of iterations with FindClusters() as described in the other answer, then choose a level which overclusters the dataset (for example, clusters that are visibly separate on a t-SNE or other dimensionality reduction … WebFeb 21, 2024 · matlab中pca输出参数对比解析 matlab中pca输出参数对比解析,[coeff,score,latent] = pca( );标准化数据输入到pca与pca输出之后标准化对比,score与coeff对比 ... nfeatures = 2000)) # 进行聚类分析 sce <- FindNeighbors(sce, dims = 1:15) sce <- FindClusters(sce, resolution = 0.5) # 绘制结果 DimPlot(sce ...
