:Select some atoms of a molecule

<p>
  We present a 3D interactive molecule (Jmol) and we ask to select certain atoms.
</p><p>
  To build an exercise with this model, just give the structure file and indicate the atoms to be selected.

:%%%%%%%%%%%%%%%%%      ATTENTION      %%%%%%%%%%%%%%%%%%%%

Remove the above header if you destroy the model tags! (The lines starting
with a ':'.) Otherwise the exercise might not be taken back by Createxo.
