Subject: Maximum and minimum box size

Dear All,

I am interested in performing a simulation where one of the box dimensions is expected to reach 50 nm. I have seen publications with 20+ nm water box sides but not sure if 50 nm or higher dimensions are supported in NAMD. I will be using MARTINI CG models. If 50 nm is supported, do I need to make any changes in the NAMD conf file?

A related question is: what is the minimum box size supported? A 1 nm distance from the sides of the solute is the ideal situation. However, if it is just a solvent box, what is the minimum supported size (for AA and CG models)?

Thank you in advance for your time and inputs.
