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