we do refinement against experimental data, not molecular dynamics ;-)
we do our simulations largely in vacuum, which means that use of
full charges can easily lead to artefacts (e.g., charged sidechains
being forced by the elec term to form a salt link even though the
density says they should each point somewhere else)
i tend to switch off elec and pele nowadays alltogether, in particular
during sa runs
