Did you know... Pse export version The pse_export_version setting switches to a legacy format when saving PSEs, so far possible. The value is the floating point number representation of the targeted legacy PyMOL version, for example 1.74 to save a session for PyMOL 1.7.4. New in PyMOL 1.7.6 Session file loading is always backwards compatible, so any newer version of PyMOL can load old session files. Examples # current version (default) set pse_export_version, 0 save current.pse # compatible with PyMOL 1.7.4 set pse_export_version, 1.74 save 174compat.pse Known Limitations The following objects are not or only partly supported: scenes before 1.7.6 (support added in 1.8.4) volumes before 1.7.2 ramps CGOs See Also save
