Each data tool has a corresponding module with the same name and functionality. The difference between the data tool and the module is that the data tool takes a CellProfiler output file (i.e., a .mat or .h5 file) as input, which contains measurements from a previously completed analysis run. In contrast, a module uses measurements received from the upstream modules during an in-progress analysis run.
Opening a data tool will present a prompt in which the user is asked to provide the location of the output file. Once specified, the user is then prompted to enter the desired settings. The settings behave identically as those from the corresponding module.
Help for each Data Tool is available under Help > Data Tool Help or the corresponding module help.
