Hai All,
I get the following warnings once i submit for minimization after inserting the protein (700 res) in dppc bilayer…Please guide me as to how should I proceed ?
WARNING: Listed nonbonded interaction between particles 11833 and 11837
at distance 6.212 which is larger than the table limit 2.050 nm.
This is likely either a 1,4 interaction, or a listed interaction inside
a smaller molecule you are decoupling during a free energy calculation.
Since interactions at distances beyond the table cannot be computed,
they are skipped until they are inside the table limit again. You will
only see this message once, even if it occurs for several interactions.
IMPORTANT: This should not happen in a stable simulation, so there is
probably something wrong with your system. Only change the table-extension
distance in the mdp file if you are really sure that is the reason.

Energy minimization has stopped, but the forces have not converged to the
requested precision Fmax < 100 (which may not be possible for your system).
It stopped because the algorithm tried to make a new step whose size was too
small, or there was no change in the energy since last step. Either way, we
regard the minimization as converged to within the available machine
precision, given your starting configuration and EM parameters.
Double precision normally gives you higher accuracy, but this is often not
needed for preparing to run molecular dynamics.
writing lowest energy coordinates.
Back Off! I just backed up system_inflated_em.gro to ./#system_inflated_em.gro.3#
Steepest Descents converged to machine precision in 15 steps,
but did not reach the requested Fmax < 1000.
