NAME

6       gmx-dyndom - Interpolate and extrapolate structure rotations

SYNOPSIS

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

DESCRIPTION

15       gmx    dyndom    reads    a   .pdb   file   output   from   DynDom   (‐
16       http://www.cmp.uea.ac.uk/dyndom/).  It reads the coordinates, the coor‐
17       dinates of the rotation axis, and an index file containing the domains.
18       Furthermore, it takes the first and last atom of the arrow file as com‐
19       mand  line  arguments (head and tail) and finally it takes the transla‐
20       tion vector (given in DynDom info file) and the angle of rotation (also
21       as command line arguments). If the angle determined by DynDom is given,
22       one should be able to recover the second structure used for  generating
23       the  DynDom  output.  Because of limited numerical accuracy this should
24       be verified by computing an all-atom RMSD (using  gmx  confrms)  rather
25       than by file comparison (using diff).
26
27       The purpose of this program is to interpolate and extrapolate the rota‐
28       tion as found by DynDom. As a result unphysical structures with long or
29       short  bonds,  or overlapping atoms may be produced. Visual inspection,
30       and energy minimization may be necessary to validate the structure.
