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. WebApr 7, 2024 · We applied the unsupervised hierarchical clustering algorithm FlowSOM (30) to our data. FlowSOM was run on a first set of three UCB and three APB samples, leading to the identification of 16 clusters grouped into 8 main populations named A to H (Supplementary Figures 5A-B and Table 1).
