I've decided to backtrack and test-run EM on a system utilizing the original
PDB file used to construct the monolayer mentioned in my last post. The
system is a DPPC bilayer composed of 64 lipid molecules and 3846 waters.
Now, when I try to run EM, no matter what parameters I choose in "em.mdp," I
keep getting the following error message (i.e. the simulation bombs):
Stepsize too small (... nm)Converged to machine precision,
but not to the requested precision (...)
Any suggestions on choosing values for "emtol," "emstep" and the number of
