Hi,
I was thinking your simulation was for just a box of water. If you have a
protein in it, then 'wrapAll on' may not be a good idea. You should do pbc,
and during analysis, make sure you calcualte distances with the
min.imagesconvention. You don't really care how you box of solvent
'looks', per se.
However, to understand why your box is getting deformed inspite of wrapAll,
you'll have to do short experimental simulations with a bunch of stuff to
see what's the issue. What did you mean by 'constraining protein to move'?
