Hello
I am running a long (5-20 ns) MD simulation with a homodimer with explicit waters. After about 4 ns I noticed that my restart files were corrupted. The coordinates in them were replaced with "********" in many places: as shown below:
18273 0.1137100E+05
-458.5618828************ 865.8784605-458.1478773************ 865.9780753- 459.5624384************ 865.9971669-458.3306444************ 864.5385748- 459.1445772************ 863.8556527-457.4029599************ 864.3070980
Thinking that the problem might be that this was an image problem with the water molecules, I started using "iwrap=1" to wrap the waters back into the box. However, after running for 500 ps or so now my homodimer has separated from each other AND translated out of the water box.
Can some one please give me some help?
I am attaching my input file.
Thanks, Steve
