ArgusLab is a program designed for molecular modeling, graphics, and drug design, specifically for Windows platforms. While it may be somewhat outdated, it continues to enjoy a surprising level of popularity with over 20,000 downloads recorded. This software is available under a free license, which means you don't have to fill out any forms to access it. Educators can utilize as many copies as necessary for their classes, allowing students to benefit from ArgusLab’s features. However, it is important to note that redistributing ArgusLab from external websites is prohibited, although linking to the official site from your own is permitted. Currently, there is a modest initiative in progress to adapt ArgusLab for use on the iPad. Additionally, efforts have been made to integrate the Qt cross-platform development environment to potentially expand compatibility across Mac, PC, and Linux systems, enhancing its accessibility for a wider audience. This commitment to adaptability underscores the software's ongoing relevance in the field of molecular modeling.

PyMOL is a molecular visualization system that operates on a user-sponsored, open-source basis, with oversight and distribution managed by Schrödinger. The PyQt interface has replaced Tcl/Tk and MacPyMOL across all platforms, enhancing the user experience significantly. This software offers improved support for third-party plugins and custom scripting, making it a comprehensive tool for rendering and animating three-dimensional structures. Additionally, it includes a plug-in that allows users to incorporate 3D images and animations directly into PowerPoint presentations. Although PyMOL is a commercial product, the majority of its source code is accessible for free under a permissive license. This open-source initiative is sustained by Schrödinger and primarily funded through the sales of PyMOL licenses. Users benefit from open access to executables and a flexible evaluation policy. Recent updates feature an improved fuse command that prevents hypervalent bonds and replaces them with monovalent atoms instead, along with a properties inspector that now allows users to unset settings using the “delete” key. Furthermore, issues regarding the workspace disappearing at certain display resolutions have also been resolved, contributing to a more seamless experience for users.

Swiss-PdbViewer, also known as DeepView, is a software tool that offers an intuitive interface for the simultaneous analysis of multiple proteins. Users can superimpose these proteins to determine structural alignments and evaluate various critical components, such as active sites. The application simplifies the process of obtaining information on amino acid mutations, hydrogen bonds, angles, and atomic distances through its easy-to-navigate graphical and menu-driven interface. Developed by Nicolas Guex since 1994, Swiss-PdbViewer was originally closely integrated with SWISS-MODEL, an automated homology modeling server created by the Swiss Institute of Bioinformatics (SIB) within the Structural Bioinformatics Group at the Biozentrum in Basel. Over time, the SWISS-MODEL web interface has progressed significantly, allowing for direct use in advanced modeling tasks. As a result, the complexity of maintaining a direct connection with Swiss-PdbViewer has led to the discontinuation of support for that integration. This evolution reflects broader changes in bioinformatics tools and their capabilities.
