NAME

6       gmx-genconf - Multiply a conformation in 'random' orientations
7

SYNOPSIS

9          gmx genconf [-f [<.gro/.g96/...>]] [-trj [<.xtc/.trr/...>]]
10                      [-o [<.gro/.g96/...>]] [-nbox <vector>] [-dist <vector>]
11                      [-seed <int>] [-[no]rot] [-maxrot <vector>]
12                      [-[no]renumber]

DESCRIPTION

15       gmx  genconf multiplies a given coordinate file by simply stacking them
16       on top of each other, like a small child playing  with  wooden  blocks.
17       The  program  makes  a  grid  of  user-defined proportions (-nbox), and
18       interspaces the grid point with an extra space -dist.
19
20       When option -rot is used the program does not check for overlap between
21       molecules  on  grid  points.  It  is recommended to make the box in the
22       input file at least as big as the coordinates + van der Waals radius.
23
24       If the optional trajectory file is given, conformations are not  gener‐
25       ated, but read from this file and translated appropriately to build the
26       grid.
