You are asking for 1.6 billion words, or 13 Gbytes of memory, and the
assertion is telling you that you don't have that much memory available.

Have you stripped out all the waters? Or is there some other reason why the
snapshots from the explicit simulation have more atoms than those from the
implicit solvent simulation? (The two systems should be the same size, and
you say that the implicit solvent system worked.)
