Sir, Thank you for the suggestion.. I will make use of it in future runs. but now the simulation is over.
There was some overlap of few ns in 8core machine. so while checking the rmsd plot there was a significant difference in rmsd between 8 core and 64 core overlapped region of simulation. 1 more question is suppose I do not have checkpoint file and if I need to continue from a stopped point (not extending) does this command do the job? $ tpbconv -s old.tpr -f traj.trr -e ener.edr -o new.tpr Because when I tried with this there was a jump in the rmsd Thank you Regards Kavya On Thu, Aug 1, 2013 at 5:18 PM, Justin Lemkul <jalem...@vt.edu> wrote: > > > On 8/1/13 3:42 AM, Kavyashree M wrote: > >> Dear Sir, >> >> First trajectory - traj1.xtc (0 to 5... ns) >> Second trajectory - traj2.xtc (5... to 25ns) >> >> But there is no gap in between. >> for concatenating - >> $ trjcat -f traj1.xtc traj2.xtc -o trajf.xtc >> >> For nujump - >> $ trjconv -f trajf.xtc -s md.tpr -pbc nojump -o trajf.xtc >> >> I also have a case where I ran 10ns in 64 cores and later >> continued in 8core machine.
