 A few other implemented flags to give better control are:
  --no-sat-corr          Don't correct values of saturated peaks using a table included in the HDF5 file.
  --only-indexed Use with -data=peaks or h5 if you want to use the peak list of only indexed patterns. (Useful for seeing changes from patterns that do not index.)
- --no-q-scaling Use with .hkl files if you want to not scale the powder by 1/q^2
+ --no-d-scaling Use with .hkl files if you want to not scale the powder by d^2
  --ring-corr            Use if you want to scale the powder plot to correct for the fractional area sampled of the powder ring. (Useful for detectors with gaps.)
  --use-redundancy       Use with .hkl files if you want to use the number of measurements and not the number of symmetrical equivalent reflections as the number of time a reflection occurs in the powder
