Subject: AMBER: GPCR membrane simulation, setting surface tension

From: Fiona McRobb (

Dear Amber Users,
I am simulating a GPCR in a DPPC membrane, using AMBER 9 and I am using the recent journal article by Jjrt, B., et al. (J. Chem. Inf. Model. 2008, 48(6), 1199-1210.) as a guide for the simulation conditions.
Following minimisation, I have heated the system to 310K using NVT ensemble. I will then be running equilibration dynamics and I am trying to determine the best type of ensemble to use, either NPT or NPT. Hence, I will be running simulations with both types of ensembles to determine which one I should use. Which brings me to my question - is it possible to set the surface tension in AMBER and if it is possible, which settings do I need to employ to achieve this? Being a new user of AMBER, I have looked through the manual extensively for the method to set the surface tension, but I have been unable to find the setting I am looking for.
Any help or suggestions would be greatly appreciated,
