Avogadro was created by Avi Frister to be a simple yet powerful molecule manipulation and analysis software. Avogadro is an innovative molecule editor and visualization tool designed specifically for the cross-platform use in molecular biology, structural biology, material science, biochemistry, and other fields. The goal of Avogadro was to build a simple to use, yet powerful and versatile molecular simulator. With Avogadro, molecules can be evaluated via simulation to study their physical properties and reaction to external stimulus under various experimental conditions. Avogadro can also be used to design and evaluate molecular interactions under non-parametric methods, such as non-thermodynamic calculation.
Avogadro's main feature is its user-friendly WYSIWYG environment for molecule simulation and visualization. This allows for both document viewing and workflow tasks such as automatic calculation, calculations with standard data representation, and automatic visualization. Since Avogadro has a WYSIWYG graphical user interface, it is easy for molecular designers to integrate the software with existing workflows. Due to Avogadro's open source nature, its functionality is supported by a large community of academic and industrial users.
The main features of Avogadro are its support for Microsoft Windows, which allows for both offline and online operation, a robust rendering engine, a simple graphical toolkit, support for multiple display formats (IBM PowerPoint, proprietary Intel Graphics tablet, etc), support for multiple programming languages (C/C++, Java, Perl, Python, etc.) and a scientific and academical data visualization and analysis package with built-in databases, data manipulation and analysis tools, as well as an efficient image processing and image rendering engine. Currently, Avogadro can be downloaded from the official site for free and they provide regular updates for life time. If you are interested in Avogadro or have questions about their product and services, they provide customer service with phone, email, chat and forum options as well.
