Screen Shots

	Visualization of beta barrel protein structure using atom sphere rendering: Each atom is rendered as a colored sphere of the Van-der-Waals radius associated with its element.
	Visualization of beta barrel protein structure using bond cylinder rendering: Covalent bonds are rendered as bi-colored cylinders of fixed radius. Hydrogen bonds are rendered as dotted yellow lines.
	Visualization of beta barrel protein structure using cartoon rendering: Alpha helices are rendered as spirals, beta strands are rendered as arrows to indicate direction, and coil regions are rendered as tubes. Hydrogen bonds are rendered as dotted yellow lines.
	Initial configuration of protein T174, a prediction target from the CASP5 protein structure prediction competition containing 417 amino acid residues, as created by ProtoShop from reading a prediction file containing only amino acid sequence and secondary structure information.
	One configuration of T174 generated using ProtoShop and manual/semiautomatic structure alignment. In this case, all ten beta strands are aligned to form a single, fully anti-parallel, beta sheet. Compact layout of alpha helices and coil regions around the constructed sheet were not attempted, since those are best handled by a global optimization algorithm.
	An alternative structure for T174 with a different strand permutation and purely parallel alignment.
	A configuration of T174 using a somewhat fancier beta barrel alignment. Again generated purely by manual interaction and without consideration for compact helix/coil arrangement.
	Close-up of beta barrel alignment for T174, with atom/atom collisions visualized as red spheres of radius proportional to penetration depth. All collisions in this structure are shallow enough to be automatically cleaned up by subsequent optimization.
	Photograph of myself manipulating an alpha-helical protein using the Virtual Reality setup on our Power Wall. Unfortunately, the Power Wall projectors do not support stereographic rendering. Update: We just started installing our new, stereo-capable, tiled display wall. It should be up and running in about two weeks or so.
