I have read that SPC/SPCE is an rigid and pre-equilibrated 3 point water
model. Is it likely mean that position restrained dynamics is not required.
If we are not intersted in position restrained dynamics then what are the
criteria for system needed.

As soon as you introduce a protein or anything else, this is no longer true.

Thank mark for comments, but I have check the structure after energy
minimization through ramachandran plot and found 82% residues were lies in
core region. After performed position restrained dynamics it reduced to 52%
in core region also 1 bad contact was found. I have taken SPC water model

Hello,
I haven't read the mails before, but as long as you are not in
equilibrium I do not think that PR coupling is the best way to go.
Furthermore PR is very sensitive to constraints and the time step, so
perhaps 2fs is too large. Try to perform a

Thank you for the discussion. I am basically having a similar problem:

Dear Sunny,
I replied a while ago, but it seems to have not made it to the list.
When using inflategro with gromacs3, you can run cycles like this:
1. inflategro.pl
2. mdrun (EM)
3. goto 1
When running with gromacs4, however, you must run cycles like this:
1. inflategro.pl
2. mdrun (EM)
3.

Hi Justin,
I just double checked and certainly the confout.gro from my EM run in
parallel with domain decomposition in mdrun is broken over periodic
boundaries.
I'm running gromacs-4.0.5 on a nehalem under openmpi. Here is my .mdp file
gpc-f101n084-$ cat em_pos.mdp

we are simulating a protein of 260 a.a length which is a trimer...How does
the MDRUN time during the PR affects the Full Dynamics results???
