Dear Gromacs users,

                                      I am planning to use tabulated
potentials for the non-bonded interactions for my system. As my system
contain some non-bonded interactions in the standard buckingham format and
some interactions are similar to buckingham ( i.e., buckingham +  some
polarization term).
Here my doubt is can we use the tables only for the interactions which
contain buckingham + polarization term and remaining interactions through
standard buckingham potential ( without tables ) ?
i.e., Is it possible to use both tables and normal standard interactions
together in gromacs ?

I have understood that atomic interactions  specified in  energygrp_tables
read potentials from specific tables and atomic interactions which are
specified in energygrps  and not specified in energygrp_table will read
potentials from general table table.xvg.
here my doubt is how about the atomic interactions which are not specified
in energygrps and energygrp_tables.
Do they read potentials from the general table table.xvg or not . Can we
use normal potentials to these interactions alone without tables.

Any help will be highly appreciated.

Thank you in advance.
