Dear All, Before when I got a MD crashed, I do the following to continue it,
"gmx tpbconv -s md_0_1.tpr -extend 0 -o md_0_1extending0ps.tpr gmx mdrun -deffnm md_0_1extending0ps -cpi md_0_1_prev.cpt -reprod -v &" Recently I have a crashed MD, and when I do "gmx tpbconv -s md_0_1.tpr -extend 0 -o md_0_1extending0ps.tpr", it says tpbconv has been replaced by convert-tpr. In "http://jenkins.gromacs.org/job/Documentation_Nightly_master/javadoc/onlinehelp/gmx-convert-tpr.html#gmx-convert-tpr";, there was introduction on convert-tpr, which says, "gmxconvert-tpr can edit run input files in four ways. 1. by modifying the number of steps in a run input file with options -extend, -until or -nsteps (nsteps=-1 means unlimited number of steps) 2. (OBSOLETE) by creating a run input file for a continuation run when your simulation has crashed due to e.g. a full disk, or by making a continuation run input file. This option is obsolete, since mdrun now writes and reads checkpoint files. Note that a frame with coordinates and velocities is needed. When pressure and/or Nose-Hoover temperature coupling is used an energy file can be supplied to get an exact continuation of the original run. 3. by creating a .tpx file for a subset of your original tpx file, which is useful when you want to remove the solvent from your .tpx file, or when you want to make e.g. a pure Calpha .tpx file. Note that you may need to use -nsteps-1 (or similar) to get this to work. WARNING: this .tpx file is not fully functional. 4. by setting the charges of a specified group to zero. This is useful when doing free energy estimates using the LIE (Linear Interaction Energy) method". My first question is, when I meet a crashed MD, can I continue it by "gmx convert-tpr -s md_0_1.tpr -extend 0 -o md_0_1extending0ps.tpr gmx mdrun -deffnm md_0_1extending0ps -cpi md_0_1_prev.cpt -reprod -v &"? My second question is, as for the introduction on convert-tpr says to continue a crashed MD by "gmx convert-tpr" was obsolete, will you please tell me the command by mdrun to directly continue a crashed MD?
