I have successfully completed a 360ns simulation, during which the time step is 30 fs.<br><br>I would like to extend the simulation to 1micro-second. The commands I used are:<br><br>$tpbconv_mpi_d -s md_360ns.tpr -extend 360000 -o md_720ns.tpr<br>
<br>$mdrun_mpi_d -s md_720ns.tpr -append -e md_360ns.edr -o md_360ns.trr -g md_360ns.log -cpi state.cpt<br><br>However, I received the following message:<br><br>Checkpoint file is from part 1, new output files will be suffixed part0002.<br>
Getting Loaded...<br>Reading file md_720ns.tpr, VERSION 4.0.3 (double precision)<br><br>Reading checkpoint file state.cpt generated: Mon Jun 14 09:48:10 2010<br><br>Loaded with Money<br><br>starting mdrun 'Protein in POPE bilayer'<br>
24000000 steps, 720000.0 ps (continuing from step 12000000, 360000.0 ps).<br>step 12000000, remaining runtime: 0 s <br>p0_6991: p4_error: interrupt SIGSEGV: 11<br><br>I have searched the mail-list, but found no similar report. I also search through google, but no answer seems satisfactory.<br>
<br>I once performed extending simulation for all atom simulation, and the method mentioned above worked.<br><br>Is anyone familiar with MARTINI CG simulation?<br>Could you give me some suggestions?<br><br>Many thanks!<br>
