label

Turn on or off labels for the four categories: atoms, bonds, angles, or dihedral angles; create and destroy simulated springs. Once a label is created (given the list of associated atoms) it can be turned on or off until it is deleted. Also, the value of the label over the trajectory can be saved to a file and viewed with an external program such as xmgrace. In the following, category implies one of [Atoms|Bonds|Angles|Dihedrals].

• list: Return a list of available categories.
• list category: List all labels in the given category.
• add category molID1/atomID1 [ molID2/atomID2... ]: Add a label involving the atom(s) atomID of the molecule molID to the given category.
• show category < all | label_number >: Turn on labels in the given category.
• hide category < all | label_number >: Turn off labels in the given category.
• delete category < all |label_number>: Delete labels in the given category.
• graph category label_number [command]: Show a graph of a label from the given category. The data will be written to a temporary file, and the specified command will be run to graph the data. %s in the command string will be replaced by the temporary filename.
• addspring molID1 atomID1 atomID2 k: Add a spring connecting the atom(s) atomID and atomID2 of the molecule molID. The spring will have spring constant k.
