+        Existing CellProfiler pipeline file *(.cppipe)* or generated by linking CellProfiler tools.

+        The input CellProfiler pipeline file *(.cppipe)* in addition to the settings of this module.

+
+        **IMPORTANT**
+
+        The first tool in a CellProfiler workflow has to be **Starting modules** and the last one **CellProfiler**. You can also execute the entire pipeline with the final CellProfiler tool, in which you feed in the images you want to process as well.
