FlowGM thus provides rapid high-dimensional analysis of cell phenotypes and is amenable to cohort studies. Greater Flexibility for Workspaces: now turn off back-gating. Cell numbers and coefficient of variation (CV) were similar between FlowGM and conventional gating for lymphocyte populations, but notably FlowGM provided improved discrimination of “hard-to-gate” monocyte and dendritic cell (DC) subsets. in 3.0 and 3.1 format for use in other analysis programs (i.e., FlowJo Software).

Cluster labels were integrated into FCS files, thus permitting comparisons to manual gating.
leukocyte population identified by back gating from CD45+ stained cells. Meta-clustering in a reference donor permitted automated identification of 24 cell types across four panels. and background fluorescence determined with FlowJo Software (FlowJo, LLC. FlowKit is a Python toolkit for flow cytometry analysis and visualization, with full support for the GatingML 2.0 standard and limited support for FlowJo 10 workspace files. A Gaussian Mixture Model (GMM)-based approach was utilized for initial clustering, with the number of clusters determined using Bayesian Information Criterion. Here, we report a computational pipeline, called FlowGM, which minimizes operator input, is insensitive to compensation settings, and can be adapted to different analytic panels. Different data analysis software, such as FlowJo or FCS Express have different. However, robust high-dimensional post-analytic strategies for automated data analysis in large numbers of donors are still lacking. Multi-parametric flow cytometry is a key technology for characterization of immune cell phenotypes.
