[url=http://www.gaussian.com/]Gaussian 03M[/url] is used by chemists, chemical engineers, biochemists, physicists and others for research in established and emerging areas of chemical interest. Starting from the basic laws of quantum mechanics, Gaussian predicts the energies, molecular structures, and vibrational frequencies of molecular systems, along with numerous molecular properties derived from these basic computation types. It can be used to study molecules and reactions under a wide range of conditions, including both stable species and compounds.
GaussViewM is a graphical user interface for Gaussian. With GaussViewM you can construct molecular systems using its molecule building facility. You can also use it to set up and run Gaussian calculations and to visualize a variety of results. GaussViewM incorporates a molecule builder for building large molecules.
[url=http://www.frogdance.dundee.ac.uk/]GelEval[/url] (shown above) is a software tool for quantifying electrophoresis gels. It can measure the densities of individual gel bands and can show the changing density along individual gel lanes. Starting from the scanned image of a gel, GelEval allows you to delimit the boundaries of individual bands and/or lanes. The total density of individual bands can then be measured. If your gel contains known standards, line-fitting is applied to express band intensity relative to the standards. Alternatively, lanes can be scanned to give a graphical representation of intensity as you move from top to bottom of the delimited region.

[url=http://www.pirx.com/]iMol[/url] is a free molecular visualization application that allows loading molecules using several file formats: PDB, MOL2, HIN, CAR, ALC, XYZ, BIO. It can handle both small and large molecules and can load multiple molecules, move and rotate them independently. iMol uses OpenGL graphics to display molecules. The molecules can be rendered using various styles. Individual atoms and/or residues can be selected and rendered independently. There are several predefined color schemes available, as well as custom colors. The rendered images can be exported as a bitmap, as a PostScript file, or as a POV-Ray file. The program can measure distances, angles, and torsional angles between atoms. Molecules can be superimposed and RMSD between atom coordinates can be calculated. Additionally, protein chains can be structurally aligned to detect regions of high structural similarity. iMol can load multimodel PDB files and display them as a dynamics trajectory.
