FindNeighbors : (Shared) Nearest-neighbor graph construction

WebHi @mistrm82, thank you for detailing your issue.Integrating the three datasets sounds like a reasonable approach to me, given these are replicates. After identifying shared clusters or cell types via integration, I would recommend finding markers which are conserved across replicates using the original merged assay, rather than the integrated assay. Web六、FindNeighbors() 首先计算每个细胞的KNN，也就是计算每个细胞之间的相互距离，依据细胞之间邻居的overlap来构建snn graph。 计算给定数据集的k.param最近邻。也可以选择(通过compute.SNN)，通过计算每个细胞最近邻之间的邻域重叠(Jaccard索引)和其邻近的k.param来构造SNN。 town and country inn and suites west ashley https://c4nsult.com

WebTo store both the neighbor graph and the shared nearest neighbor (SNN) graph, you must supply a vector containing two names to the graph.name parameter. The first element in the vector will be used to store the nearest neighbor (NN) graph, and the second element used to store the SNN graph. If only one name is supplied, only the NN graph is stored.
