[gmx-users] Extending MD run

[teklebrh at ualberta.ca]

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

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

what does the -extend means?

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

Please give me some suggestions.

Rob
