This menu option is only shown if specified in the Preferences. Note that if this preference setting is changed, CellProfiler must be restarted.
Using this plugin will allow you sample a range of setting values in IdentifyPrimaryObjects and save the object identification results for later inspection. Upon completion, the plug-in will generate a text file, which specifies: (1) all unique combinations of the sampled parameter values; (2) the mapping from each combination of parameter values to one or more output images; and (3) the actual output images.
More information on how to use the plugin can be found here.
