gmx genconf¶
Synopsis¶
gmx genconf [-f [<.gro/.g96/...>]] [-trj [<.xtc/.trr/...>]]
[-o [<.gro/.g96/...>]] [-nbox <vector>] [-dist <vector>]
[-seed <int>] [-[no]rot] [-maxrot <vector>]
[-[no]renumber]
Description¶
gmx genconf multiplies a given coordinate file by simply stacking them
on top of each other, like a small child playing with wooden blocks.
The program makes a grid of user-defined
proportions (-nbox),
and interspaces the grid point with an extra space -dist.
When option -rot is used the program does not check for overlap
between molecules on grid points. It is recommended to make the box in
the input file at least as big as the coordinates +
van der Waals radius.
If the optional trajectory file is given, conformations are not generated, but read from this file and translated appropriately to build the grid.
Options¶
Options to specify input files:
-f[<.gro/.g96/…>] (conf.gro)- Structure file: gro g96 pdb brk ent esp tpr
-trj[<.xtc/.trr/…>] (traj.xtc) (Optional)- Trajectory: xtc trr cpt gro g96 pdb tng
Options to specify output files:
Other options:
-nbox<vector> (1 1 1)- Number of boxes
-dist<vector> (0 0 0)- Distance between boxes
-seed<int> (0)- Random generator seed (0 means generate)
-[no]rot(no)- Randomly rotate conformations
-maxrot<vector> (180 180 180)- Maximum random rotation
-[no]renumber(yes)- Renumber residues
Known Issues¶
- The program should allow for random displacement of lattice points.
