Size and classified by a t-number or a Tilingannäherung R. icosahedral the symmetry imposes a fold 60 60 degeneration of the information, those differentiates between the determination of a three-dimensional makes possible structure of straight unites pictures. Most packages for the analysis of icosahedral structures use a Fourier Bessel approach contrary to other individual particle of packages, which use material space algorithms, mainly the method of the back projection. Packages such as IMAGIC-5, SPIDER, EMAN and Xmipp uses for analysis of individual particle pictures also low or no symmetry. These packages use thousands of pictures individual molecules. The software makes CTF for correction possible, picture adjustment, determining position determination and the computation of three-dimensional reconstructions.
Situs, URO, MOLREP, EMfit are packages, those for the interpretation to be used can and objective attachment of data. O and PyMOL uses mainly for manual attachment and control of data. The software, which uses, in order to represent results, covers: Surface representation (shade) Amira, screen researcher, PyMol, Schimäre. Amira is a system of the advanced software for Sichtbarmachung 3D. Screen researcher is efficient software, which is particularly useful for surface shade and density interpretation. PyMOL is a molecular diagram system with an embedded index author, and Pythonschlangeinterpret is sketched to animations, for real time visible making and fast production of the high-quality molecular diagram pictures and -. It makes possible to draw up and fit from the VEH coordinates into three-dimensional diagrams. Schimäre is an interacting molecular diagram program.
