Reflex module for Nafion?

Hi!

     I am try to setup Nafion membrane system for MD test. After building the cell, I wish to compare the XRD pattern with experiment's result.

But from Reflex simulation, the are many sharp peak. It is quite different for experiment that just two major broad peaks.

    Are there any setting should be modify, or the Reflex module doesn't work for polymer system?
