# Note that if you are working on the analysis development locally, i.e. outside
# of the REANA platform, you can proceed as follows:
#
#   $ cd reana-demo-worldpopulation
#   $ mkdir -p yadage-local-run/yadage-inputs
#   $ cd yadage-local-run
#   $ cp -a ../code ../data yadage-inputs
#   $ yadage-run . ../workflow/yadage/workflow.yaml \
#        -p notebook=code/worldpopulation.ipynb \
#        -p input_file=data/World_historical_and_predicted_populations_in_percentage.csv \
#        -p region=Africa \
#        -p year_min=1500 \
#        -p year_max=2012 \
#        -d initdir=`pwd`/yadage-inputs
#   $ firefox worldpopulation/plot.png
