This might be the solution.
Thank you,

If I am understanding correctly, then for your application it sounds like you should consider setting iwrap=0 so the coordinates are not imaged when amber writes the restart and trajectory files so your calculations can be run more easily and avoid breaking your restraints. By setting iwrap=0, the primary unit cell will look like the solvent is evaporating, but it's totally fine when considering periodicity. You can always later go back and image the system to make a "clean looking" unit cell to prepare figures and presentations. But the point of setting iwrap=0 is to prevent multiple solute molecules from imaging to opposite sides of the unit cell when applying restraints that don't consider periodicity. -Tim
