================ Post-processors ================ This document explains the purpose of post-processors and lists the different available post-processors and the requirements each has to be used effectively. What is a post-processor? ------------------------- A postprocessor is a function that takes the results from the impact function and calculates derivative indicators, for example if you have an affected population total, the **Gender** post-processor will calculate gender specific indicators such as additional nutritional requirements for pregnant women Selecting a post-processor -------------------------- Post-processors and their settings can be edited in the user configurable function parameters dialog. To disable a post-processor simply change the :guilabel:`Postprocessors` :samp:`"'on': True" to "'on': False"`. The same is valid for any other setting you might encounter there. If you don't see a post-processors field, it means that the impact function you are trying to use does not support any post processor .. figure:: ../static/postprocessor-config.png :align: center Each activated post-processor will create an additional report in the dock and in the printout. If problems arise while post processing, the system will inform you and will skip post-processing. Creating post-processors ------------------------ If you feel there is an important post-processor which is missing, there are two avenues you can follow: * You can develop it yourself or with the aid of a programmer who has a good understanding of the python programming language. * You can file a ticket on our `issue tracking system `_, and if time and resources allow we will implement it for you.
