Hi Justin ,
Thank you for immediate reply and providing the link.
But I am wonder for following things...
For protein simulation in your lysozyme tutorial we use
refcoord_scaling = com
In lipid tutorial also same one..
So Is there are any case when to use
refcoord_scaling no or all .....??????
Depends whether rigidity or scaling make more sense in your model of
real physics, which depends what's in your system.
Is there any way to find out which option to use when????
Thinking about it :-)
How all the things going to affect the result????
I goes trough archive but not find satisfactory answer...
I am looking for clear and simple explanation...
Using position restraints ensures you do not reach the NPT ensemble.
Whatever option you choose, you will need to simulate further without
your position restraints to reach equilibrium. You should focus on
minimizing the need for them, by making your system have the right
density to start with. Then the volume change will be negligible, and
the difference between these options likewise.
