# 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-root6-roofit
#   $ mkdir -p yadage-local-run/yadage-inputs
#   $ cd yadage-local-run
#   $ cp -a ../code yadage-inputs
#   $ yadage-run . ../workflow/yadage/workflow.yaml \
#        -p events=20000 \
#        -p gendata=code/gendata.C \
#        -p fitdata=code/fitdata.C \
#        -d initdir=`pwd`/yadage-inputs
#   $ firefox fitdata/plot.png
