PyMOL v1.8.2 Release Notes

Release Date: Apr-20-2016

Incentive Features moved to Open-Source

  • iterate exposes atom-level settings (e.g. s.sphere_scale), Incentive feature since PyMOL 1.7

New Settings

  • cartoon_gap_cutoff: draw dashed cartoon over gaps of size < cartoon_gap_cutoff
  • auto_show_classified: When loading a file, show cartoon for polymer, sticks for organic, and spheres for inorganic molecules (Setting > Auto Show… > … by Classification)
  • ignore_case_chain setting (ignore_case=1 default restored in
  • collada_background_box (off by default, previous versions unconditionally created a large box to mimic the scene background color)

File Import/Export

  • support atom name/resn/segi with more than 4 letters (e.g. from CIF files)
  • MOL2
    • loading
      • improve resn reconstruction from subst_name
      • improve formal_charge guessing
    • export
      • write SUBSTRUCTURE record for chain support
  • MAE loading: sort atoms
  • amber topology loading: set all bond orders to 1 instead of 0


  • new “Distances between rings” measurement mode in Measurements Wizard
  • new “byring” selection operator
  • new distance mode=4: distance between centroids
  • cartoon representation
    • cartoon dash: New loop-like cartoon type which skips every second segment
    • auto-detect CA-only models for cartoon and ribbon (no cartoon_trace_atoms needed)
  • enable ignore_case and ignore_case_chain for “rms” and “update”
  • grid_mode=3: prid per object-state


  • iterate/alter
    • list(s) → list of atom-level setting indices (or atom-state-level settings with iterate_state)
    • improve exception handling and error reporting
    • disable automatic text_type assignment with atom_type_format=““ (empty string)
