WebCluster Explorer is a FlowJo plugin. The tool creates an interactive cluster Profile graph, heatmap, and displays the cluster populations on a tSNE/UMAP plot. The plots are dynamic, can be copied to the clipboard or FlowJo Layout, and allow the user to select populations in one view and highlight the selected population in the other plots.

WebMany different clustering methods and dimension reduction techniques are available for flow cytometry data . In this paper, we only show the use of UMAP and FlowSOM. For flow cytometry, FlowSOM clustering seems to be the best performing algorithm (11, 28). Furthermore, we prefer UMAP to explore our data and visualize marker expression … WebFlowSOM Algorithm. FlowSOM analyzes flow or mass cytometry data using a self-Organizing Map (SOM). Using a two-level clustering and star charts, FlowSOM helps to obtain a clear overview of how all markers are behaving on all cells, and to detect subsets that might be missed otherwise. The algorithm consists of four steps: reading the data
