# csg\_density(1)

Part of the VOTCA package

## NAME

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

## SYNOPSIS

**csg\_density** \[OPTIONS\]

**csg\_density** \[--help\]

## DESCRIPTION

Calculates the mass density distribution along a box axis or radial density profile from reference point

## 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

Mapping options:

  \--cg arg                  \[OPTIONAL\] coarse graining mapping and bond \
                           definitions\
                             (xml-file). If no file is given, program acts on \
                           original trajectory\
   \--map-ignore arg          list of molecules to ignore if mapping is done \
                           separated by ;

Specific options::

  \--type arg (=mass)      density type: mass or number\
   \--axis arg (=r)         \[x\|y\|z\|r\] density axis (r=spherical)\
   \--step arg (=0.01)      spacing of density\
   \--block-length arg        write blocks of this length, the averages are \
                           cleared after every write\
   \--out arg               Output file\
   \--rmax arg              rmax (default for \[r\] =min of all box vectors/2, else\
                           l )\
   \--scale arg (=1)        scale factor for the density\
   \--molname arg (=\*)      molname\
   \--filter arg (=\*)       filter bead names\
   \--ref arg               reference zero point

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
