The Selection Tool

The selection tool allows the indiviual selection of atoms, bonds, or fragments.

There are three types of selection modes: "Atom/Bond", "Residue", and "Molecule".

The "Atom/Bond" selection mode provides you with the ability to select a single atom within a molecule. This is achieved by left clicking the atom. Pressing down the "Shift" button on your keyboard allows the selection of multiple atoms.

Right clicking on the black display will clear the selection made.

The "Residue" selection mode will select an entire residue within the molecule, by clicking on a single atom in the residue.

The "molecule" selection mode will select the entire molecule by clicking on an atom. Double clicking the molecule will also select the entire molecule.

Molecules can also be selected by clicking and dragging your cursor across the display.

Clicking on "Add Center of Atoms" will display a black ball where the center of the molecule is found.

Clicking on the "Add Center of Mass" will display a black ball where the center of mass of the molecule is found.
