TVIA: Tools for Visual Information in Molecular Scene Analsys

Despite the technological advances of the last few years, protein structure determination has remained a lengthy and complex task. Advances in methods protein structure prediction have also been great, but prediction tertiary structure from amino acid sequence alone remains remains a perhaps distant goal. As a result, only a small fraction of the currently known macromolecular structures have been fully characterized. The determination of crystal structures from their diffraction data belongs to the general class of image reconstruction exercises from incomplete and/or noisy data. In the case of protein structures, a major hurdle in the image reconstruction process is the phase problem. The solution of this problem currently relies on gathering extensive diffraction data through, for example, isomorphous replacement or anomalous scattering experiments. It also relies on considerable input from experts who use their ability to recall structural templates, along with the known rules of chemistry and crystallography, to interpret the developing molecular image.
