Hierarchical clustering seurat
WebClustering and classifying your cells. Single-cell experiments are often performed on tissues containing many cell types. Monocle 3 provides a simple set of functions you can use to group your cells according to their gene expression profiles into clusters. Often cells form clusters that correspond to one cell type or a set of highly related ... The development of single-cell RNA sequencing (scRNA-seq) and bioinformatics technologies have accelerated the understanding of cell heterogeneity (Aldridge and Teichmann, 2024). The current practice for studying the multi-level cell heterogeneity is to first produce a fixed number of clusters and then adjust the … Ver mais HGC contains two major steps: graph construction and dendrogram construction. For the graph construction step, HGC adopts the standard procedure of building the SNN graph, which is to first apply principal component … Ver mais We developed a new method HGC and its R package for fast HC of single-cell data. It can reveal the hierarchical structure underlying the data, achieves state-of-the-art clustering accuracy and can scale to very large single-cell … Ver mais This work was supported by the NSFC Projects (61721003 and 62050178) and National Key R&D Program of China (2024YFC0910401).
