The error message basically says you need to add the 'step' property
for the interaction 'bond'.
You can to so by either adding "--step XXX" to your command line, e.g.
$  csg_call --ia-type bond --ia-name bond --options bond.xml
convert_potential gromacs --step 0.01 bond1_extrapolate.pot
table_b1.xvg
(see "csg_call onvert_potential gromacs --help" for more details)
or add block like:
  <bonded>
    <name>bond</name>
    <min>0</min>
    <max>1.0</max>
    <step>0.001</step>
  </bonded>
inside the <cg> block of your bond.xml.

Cheers,

Christoph
