 	<P/>The next command reads in the pdb file for the  T.thermophilus 1V2X protein and represents it as a <M>3</M>-dimensional pure cubical complex <M>K</M>. A resolution of <M>r=5</M> is chosen and this results in a representation as a subcomplex <M>K</M> of an ambient rectangular box of volume equal to <M>184\times 186\times 294</M> unit cubes. The complex <M>K</M> should have the homotopy type of a circle and the protein backbone is a 1-dimenional curve that should lie  in <M>K</M>. The final command displays <M>K</M>.
