Re: [gmx-users] How to extend my incompleted simulation? (not extend a completed one)
Sorry, didn't notice the cpt files weren't yet generated. Justin is always right about everything. Alex On 12/29/2016 1:58 PM, Zhang, Cheng wrote: Hi Justin, Thank you very much.

In my case, I want to continue a incompleted job. If you have no .cpt file, then you can only restart the job from the beginning. Your previous command of "mdrun -deffnm md_0_1" will not have produced anything called "state.cpt" so your above command will only start over from the beginning of the simulation (and the .log file should note this, otherwise check stdout/stderr). Any run terminated prematurely can be continued simply by adding "-cpi -append" to the previous command, assuming a .cpt file is present. If one is not present, then either the run crashed before writing it (again, check the .log or stdout/stderr for obvious error messages) or the cluster cut the job off before the -cpt interval (default: 15 minutes) was reached. -Justin Thank you.

Re: [gmx-users] How to extend my incompleted simulation? (not extend a completed one)
add "-cpi state.cpt -append " into your mdrun command and submit it.
