# csg\_map(1)

Part of the VOTCA package

## NAME

**csg\_map** - Part of the VOTCA package

## SYNOPSIS

**csg\_map** \[OPTIONS\]

**csg\_map** \[--help\]

## DESCRIPTION

Convert a reference atomistic trajectory or configuration into a coarse-grained one  based on a mapping xml-file. The mapping can be applied to either an entire trajectory  or a selected set of frames only (see options).\
   \* csg\_map --top FA-topol.tpr --trj FA-traj.trr --out CG-traj.xtc --cg cg-map.xml\
   \* csg\_map --top FA-topol.tpr --trj FA-conf.gro --out CG-conf.gro --cg cg-map.xml\
   \* csg\_map --top FA-topol.tpr --trj FA-traj.xtc --out FA-history.dlph --no-map\
   \* csg\_map --top FA-field.dlpf --trj FA-history.dlph --out CG-history.dlph --cg cg-map.xml\
   \* csg\_map --top .dlpf --trj .dlph --out .dlph --cg cg-map.xml  convert HISTORY to HISTORY\_CGV

## OPTIONS

Allowed options:

    \-h \[ --help \]             display this help and exit\
     \--verbose                 be loud and noisy\
     \--verbose1                be very loud and noisy\
     \-v \[ --verbose2 \]         be extremly loud and noisy\
     \--top arg                 atomistic topology file\
     \--out arg                 output file for coarse-grained trajectory\
     \--vel                     Write mapped velocities (if available)\
     \--force                   Write mapped forces (if available)\
     \--hybrid                  Create hybrid trajectory containing both atomistic \
                             and coarse-grained\
   Mapping options:

    \--cg arg                  coarse graining mapping and bond definitions \
                             (xml-file)\
     \--map-ignore arg          list of molecules to ignore separated by ;\
     \--no-map                  disable mapping and act on original trajectory\
   Trajectory options:

    \--trj arg                 atomistic trajectory file\
     \--begin arg (=0)          skip frames before this time (only works for \
                             Gromacs files)\
     \--first-frame arg (=0)    start with this frame\
     \--nframes arg             process the given number of frames
