    <name>inverse.espresso.table</name>
    <desc>
      Name of file for tabulated potential of this interaction. This file will
be created from the internal tabulated potential format for every run. Note,
though, that the original espresso blockfile needs to contain the name of that
table as the tabulated interaction (see tutorial methanol ibi_espresso for details).

  <item>
    <name>fmatch.min</name>
    <desc>
      Minimum value of interval for distribution sampled in atomistic MD simulation. One can get this
      number by looking at the distribution function for this interaction. For non-bonded interactions
      it's the distance to the rdf start. For CG bonds and angles the variable has the similar meaning
      ( note, that for angles it is specified in radians ).
    </desc>
  </item>
  
  <item>
    <name>fmatch.max</name>
    <desc>
      Maximum value of interval for distribution sampled in atomistic MD simulation. One can get this
      number by looking at the distribution function for this interaction. For non-bonded interactions
      it's the cut-off of the interaction.
    </desc>
  </item>

  <item>
    <name>fmatch.step</name>
    <desc>
      grid spacing for the spline, which represents the interaction. This parameter should not be too big,
      otherwise you might lose some features of the interaction potential, and not too small either, otherwise you
      will have unsampled bins which result in an ill-defined equation system and NaNs in the output.
    </desc>
  </item>

  <item>
    <name>fmatch.out_step</name>
    <desc>
      Grid spacing for the output grid. Normally, one wants to have this parameter smaller than fmatch.step, 
      to have a smooth curve, without additional spline interpolation. As a rule of thumb we normally use
      fmatch.out_step which is approximately 5 times smaller than fmatch.step.
