Thank you Justine

I have another question. I run my simulation for 5ns and when i just check the density of my solvent, the density did not look right. I used the N-H and P-R for the thermostat and barostat. Both shows the correct temperature and pressure (300K and 1bar). when I use the g_density to check only the density of my solvent (in this case Toluene), it shows 0.933g/ml, but the actual density according to literature is 0.866g/ml. I have no idea what the problem is.

Can you please give me some suggestions.

Dear Gromacs users,

I am using gromacs 3.3.3 for my simulation.

I run my project for 5ns and want to extend to 10 ns. Can any body tell me if this is the right way to do.

tpbconv -s previous.tpr -f previous.trr -e previous.edr -o next.tpr -extend timetoextend


Being that you've copied the entry from here:

http://www.gromacs.org/Documentation/How-tos/Extending_Simulations

...I would guess that it's correct :)

The previous.tpr means for the 5ns MD run.
The next.tpr is for the 10ns.

what does the -extend means?


Per tpbconv -h:

"Extend runtime by this amount (ps)"

-Justin

what does timetoextend means ( in my case is timetoextend is 5ns)

Please give me some suggestions.

Rob
