Rlabel displays labels containing residue name and specifier for residues with any atom in atom-spec. (Residue labels containing other information can be displayed using the Actions menu.) A residue label is placed at the centroid of the displayed atoms in the residue. When ribbon is displayed instead of mainchain atoms, mainchain atom positions are still used in computing the centroid. Label font and size can be set in the Background preferences.
Rlabel differs from the original Midas command, which merely allowed residue information to be shown if a residue had one or more atom labels.
~Rlabel removes residue labels.
