Label categories

 

The Category chooser (in the upper left) is used to select which category of labels to manipulate. The different label categories include:

• Atoms, which are shown as a text string next to the atom listing the name and residue of the atom;
• Bonds, which are shown as dotted lines between the atoms with the bond length displayed at the bond midpoint; 
• Angles, which are shown as dotted lines between the three atoms with the angle displayed at the center of the defined triangle; 
• Dihedrals, which are shown as dotted lines between the four atoms with the dihedral angle (the angle between the planes formed by the first three atoms and the last three atoms) shown at the midpoint of the torsional bond.
• dihedrals

All the labels for the selected category which have been previously added are displayed in the browser in the center of the form. The line itself contains from 1 to 4 atom names, depending on the category; the atom names have the form

followed by either (on) or (off). The last word indicates if the label is turned on or off.
