NAME

       gmx-dyndom - Interpolate and extrapolate structure rotations

SYNOPSIS

          gmx dyndom [-f [<.pdb>]] [-n [<.ndx>]] [-o [<.xtc/.trr/...>]]
                     [-firstangle <real>] [-lastangle <real>] [-nframe <int>]
                     [-maxangle <real>] [-trans <real>] [-head <vector>]
                     [-tail <vector>]

DESCRIPTION

       gmx  dyndom  reads  a .pdb file output from DynDom (http://www.cmp.uea.ac.uk/dyndom/).  It
       reads the coordinates, the coordinates of the rotation axis, and an index file  containing
       the  domains.   Furthermore, it takes the first and last atom of the arrow file as command
       line arguments (head and tail) and finally it  takes  the  translation  vector  (given  in
       DynDom info file) and the angle of rotation (also as command line arguments). If the angle
       determined by DynDom is given, one should be able to recover the second structure used for
       generating  the  DynDom  output.   Because  of  limited  numerical accuracy this should be
       verified by computing an all-atom RMSD (using gmx confrms) rather than by file  comparison
       (using diff).

       The  purpose  of  this  program is to interpolate and extrapolate the rotation as found by
       DynDom. As a result unphysical structures with long or short bonds, or  overlapping  atoms
       may  be  produced. Visual inspection, and energy minimization may be necessary to validate
       the structure.
