You can run it manually as follows

ewoks execute examples/rebinsum.json \
    -p wait:filename=/path/to/data.h5 \
    -p 'wait:entries=["1.1","2.1"]' \
    -p rebin:delta2theta=0.003
    -p sum:binsize=0.002

Workflow parameters are specified by the pattern -p ID:NAME=VALUE where ID is the id of the node in the graph (see above) and NAME is the name of the parameter to be set.
