These are relatively old materials to be downloaded. More recent scripts etc. coming soon. In particular, operations on GRO files will be available.

Scripts

  • Radial distribution function: gr.py
  • Histogram: histogram.py
  • Extraction of positions of defined atoms along xyz trajectory: xyz_position.py
  • Calculation of the distance of a given atom from system's center along xyz trajectory: xyz_distance_from_center.py
  • Fixing an atom at a given position along an xyz trajectory: xyz_fix_atom.py
  • Fixing a given bond orientation along an xyz trajectory: xyz_fix_bond.py
  • Calculation of an angle between a plane and the z-axis along an xyz trajectory – quite useful for planes on interfaces: xyz_angle.py
