[gmx-users] low concentration simulation ?

2010-01-05 Thread Chih-Ying Lin
HI I am simulating the protein + ligand + water molecules system. In the experimental work, the concentration of ligand is pretty low, say under 20 mM (avearge 18 ligands attached on one protein) It will be a huge system to create a system with 20 mM and it will take lot of simulation time.

Hi From Justin, If you say that you have 20 mM of ligand, which corresponds to 18 ligands attached to one protein, why not just put 18 molecules in your unit cell with one protein? = I want to save the simulaiton time since i will run the simulation up to 1 micro-sencond. = 18 ligand + one
