This directory contains the makefiles used to execute the analyses described below. To execute any of the workflows:

1. Update the relevant config.mk file with your directory structure and desired options/settings
2. Replace the TARGET in the config.mk file with a target taken from one of the other makefiles related to that workflow
3. Run the workflow: e.g. make -n -B -f zw_applications.mk
   (-n is a dry run where what would have been executed is just printed to the screen)
   (-B forces all the steps to be executed, not just the ones that need updating)
