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 WebApr 13, 2024 · The tSNE plots in top panels display cell density and represent the pooled data for each group, while the lower panel shows a projection of the FlowSOM clusters on a tSNE plot. Heatmaps show the median marker expression for each FlowSOM cluster (C). Differentially abundant populations were identified by CITRUS among gated monocytes.
