PyMOL SyntaxError: 'JumpDefinition' Invalid Command - How to Fix

This error message indicates a syntax error in your PyMOL command: 'JumpDefinition my_pose A 462 CA X 1 CA'.

The command 'JumpDefinition' is not a valid PyMOL command. Additionally, arguments like 'my_pose' and 'X' are not recognized by PyMOL.

To create a jump between specific atoms using PyMOL's built-in 'jump' command, use the following syntax:

jump my_pose, resi 462 and name CA, resi 1 and name CA

This command creates a jump between the CA atoms of residue 462 and residue 1 in the current object. Note that:

• 'my_pose' is not necessary as PyMOL automatically assigns names to objects.
• 'X' is not a valid argument and should be removed.

Remember to load a structure into PyMOL before using the 'jump' command.
