AMBER users,
I was hoping that somebody could clarify something that I found in an AMBER tutorial. In this tutorial:
http://www.rosswalker.co.uk/tutorials/amber_workshop/Tutorial_one/section5.htm
it says:
"Using constant pressure with restraints can also cause problems so initially we will run 20 ps of MD at constant volume."
I am working with a system where it is really necessary to use restraints on about one third of the solute. I had planned on using ntr=1 with a force constant of 10 kcal/mol. Could someone please specify what the risks are of combining restraints with constant pressure, and how I can minimize those risks?
Thank you very much for your help.
Josh
