12 test convert-tpr can edit run input files in three ways.
14 1. by modifying the number of steps in a run input file with options -extend,
15 -until or -nsteps (nsteps=-1 means unlimited number of steps)
17 2. by creating a .tpx file for a subset of your original tpx file, which is
18 useful when you want to remove the solvent from your .tpx file, or when you
19 want to make e.g. a pure Calpha .tpx file. Note that you may need to use
20 -nsteps -1 (or similar) to get this to work. WARNING: this .tpx file is not
23 3. by setting the charges of a specified group to zero. This is useful when
24 doing free energy estimates using the LIE (Linear Interaction Energy) method.
28 Options to specify input files:
30 -s [<.tpr/.gro/...>] (topol.tpr)
31 Run input file to modify: tpr gro g96 pdb brk ent
32 -n [<.ndx>] (index.ndx) (Opt.)
33 File containing additional index groups
35 Options to specify output files:
37 -o [<.tpr/.gro/...>] (tprout.tpr) (Opt.)
38 Generated modified run input file: tpr gro g96 pdb brk ent
43 Extend runtime by this amount (ps)
45 Extend runtime until this ending time (ps)
47 Change the number of steps
49 Set the charges of a group (from the index) to zero
