Load restores a saved session (see the save command). If session_name is omitted, a dialog for specifying the name and location will appear. A session file consists of Python code that reconstitutes the state of Chimera by displaying data and performing other operations.
Molecular coordinate and sequence alignment data are included in the session file; however, volume data files must still be present to restart a session in which they were open. When a session with volume data is restarted, the user may be queried about file location(s) if the data or the session file have been moved since the session was saved.
There are multiple ways to save sessions and restart sessions.
