Labelling and annotation All labelling and annotation options are reset with Rset or on moving to a new entry with the exception of the Labl menu toggle. Individual atoms may be labelled by clicking on the atom position in the plot. Menu Buttons Labl draws labels for all atoms in current plot. Nola draws no labels for atoms, molecules or residues. Nodi removes distances and angles from the plot and clears the distance key in the top left corner of the plot.
Title allows a title to be typed which is displayed in the bottom left corner of the plot.
Text allows text to be typed to annotate plot. Select position for start of text and then type text. Existing text can also be selcted for moving or deletion. This may be useful in identifying an atom uniquely for a typed command since several atoms may have the same label in a packing diagram. Zoom- magnifies the current image by a factor of 0.9.
