For refinement, you can follow eginput/gb1_rdc/refine_eefx.py, for
modifying an EnsembleSimulation script to replace repel with EEFx,
with one difference. Briefly, to the top of your script (before
loadPDB or initParams):

import eefxPotTools 
eefxPotTools.initEEFx()

Then, replace the XPLOR VDW setup with an ensemble-averaged EEFXPot term:

#nonbonded term
from eefxPotTools import create_EEFxPot
eefxpot=AvePot(create_EEFxPot("eefxpot",selection=AtomSel('not PSEUDO',
                                                          esim.member())))
potList.append(eefxpot)
rampedParams.append(MultRamp(0.1,1.0,"eefxpot.setScale(VALUE)"))

Please let me know if you have problems with this.
