Abstract

Herein we present the VMD Store, an open-source VMD plugin that simplifies the way how users browse, discover, install, update, and uninstall extensions for the Visual Molecular Dynamics (VMD) software. The VMD Store obtains data about all the indexed VMD extensions hosted on GitHub and presents a one-click mechanism to install and configure VMD extensions. This plugin arises in an attempt to aggregate all VMD extensions in a single platform. The VMD Store is available, free of charge, for Windows, macOS, and Linux at https://biosim.pt/software/, and requires VMD 1.9.3 (or later).

Desenvolvimento de Software com Aplicação no Ensino Em Química e Biologia – VII Encontro da Divisão de Ensino e Divulgação da Química

Last Saturday (November 17th), I was presenting some of the software that we have developed at BioSIM research group to improve the way some chemical concepts are taught to our students.

VMD extensions, such as VMD Magazine, ToolBar, Protein Wars, and VMD Store were presented during the “VII Encontro da Divisão de Ensino e Divulgação da Química” conference. During the presentation, the software features were presented and were showed how these extensions can be used to engage young students to learn chemistry in a more pleasant and clear manner.

Moreover, the BioSIM Augmented Reality technology was presented for the first time, and it allows an easy and costless way to see molecules using augmented reality. See the video below:

Feira de Ciência – New Software Applications for Biomolecular Simulations

New Software Applications for Biomolecular Simulations: Applications to Chemistry and Biochemistry.

CHEMTECH DQB – Chemistry Technology Events at DQB – 2018

March 8th, 2018 – Departamento de Química e Bioquímica da Faculdade de Ciências da Universidade do Porto

Descrição da Atividade

Realizou-se no Departamento de Química e Bioquímica da Faculdade de Ciências da Universidade do Porto uma mini feira de ciência onde se mostraram os softwares desenvolvidos no grupo de Bioquímica Teórica e Computacional. Os softwares são todos eles extensões para o VMD (Visual Molecular Dynamics) um visualizador molecular gratuito desenvolvido pela Universidade Illinois.

Os participantes tiveram a oportunidade de falar com os desenvolvedores e experimentar os softwares, que sendo gratuitos podem ser mais tarde instalados e usados por cada um dos participantes.

Fica aqui o folheto que foi distribuído na sessão demonstrativa: Download

Abstract

The notable advances obtained by computational (bio)chemistry provided its widespread use in many areas of science, in particular, in the study of reaction mechanisms. These studies involve a huge number of complex calculations, which are often carried out using the Gaussian suite of programs. The preparation of input files and the analysis of the output files are not easy tasks and often involve laborious and complex steps. Taking this into account, we developed molUP: a VMD plugin that offers a complete set of tools that enhance the preparation of QM and ONIOM (QM/MM, QM/QM, and QM/QM/MM) calculations. The starting structures for these calculations can be imported from different chemical formats. A set of tools is available to help the user to examine or modify any geometry parameter. This includes the definition of layers in ONIOM calculations, choosing fixed atoms during geometry optimizations, the recalculation or adjustment of the atomic charges, performing SCANs or IRC calculations, etc. molUP also extracts the geometries from the output files as well as the energies of each of them. All of these tasks are performed in an interactive GUI that is extremely helpful for the user. MolUP was developed to be easy to handle by inexperienced users, but simultaneously to be a fast and flexible graphical interface to allow the advanced users to take full advantage of this plugin. The program is available, free of charges, for macOS, Linux, and Windows at the PortoBioComp page https://www.fc.up.pt/PortoBioComp/database/doku.php?id=molup.
