the choice of FullSamples inherently depends on the nature of your system
and the choice of your reaction coordinate. If it is a slow degree of
freedom, then a large FullSamples might be required to ascertain that the
average force has converged towards the desired value. Excessively small
FullSamples would yield undesirable non-equilibrium effects and unphysical
biasing forces. You can monitor the convergence of the average force in
the force distribution histograms generated for every bins. This aspect of
ABF is documented in:
Exploring the free-energy landscape of a short peptide using an average
force. J. Chem. Phys. 2005, 123(24), 244906.
