NAME

tpbconv - makes a run input file for restarting a crashed run

VERSION 4.0.1

SYNOPSIS

tpbconv -s topol.tpr -f traj.trr -e ener.edr -n index.ndx -o tpxout.tpr -[no]h -nice int -nsteps int -runtime real -time real -extend real -until real -[no]zeroq -[no]cont

DESCRIPTION

tpbconv can edit run input files in four ways.

1st. by modifying the number of steps in a run input file with option -nsteps or option -runtime.

2st. (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 This option is obsolete, since mdrun now writes and reads checkpoint files.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.

3nd. 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 Ca tpx file. WARNING: this tpx file is not fully functional. 4rd. 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.
