The goal of Flow Cytometry: Critical Assessment of Population Identification Methods (FlowCAP) is to advance the development of computational methods for the identification of cell populations of interest in flow cytometry data. FlowCAP will provide the means to objectively test these methods, first by comparison to manual analysis by experts using common datasets, and second by prediction of a clinical/biological outcome.
