Accelrys Discovery Studio Visualizer

Software for 3D visualization and analysis of biomolecules.

DS Visualizer is an application for analysis and 3D visualization of macromolecules (proteins, RNA, DNA). Its particular strength lies in the intuitive usage as a structure analysis tool: There is no need for reading documentations, just start viewing and manipulating PDB structures in one of the best designed UIs for 3D representations. Simply expand the tree view on the left of the 3D molecule view to select chains or residues down to the single atoms. The selection can be done in the 3D view as well. Selected objects are always highlighed in both places. It's the perfect tool for also for beginners and useres who rarely work with 3D software for visualization of macromolecules.

Adobe Illustrator

Adobe illustrator is a vector graphics application that allows for clean and simple image creation (in 2D).

Adobe illustrator facilitates the creation of logos, drawings, typography, illustrations and, of course, figures for papers as well as group webpages and other applications. Because illustrator artwork is vector based, it can scale up and down easily for different sized screens and thus is valuable for material published on the web. It is possible to create freehand drawings as well as recolor imported photos (rendering the additional use of Photoshop unnecessary for figures). Furthermore, it is possible to import graphs from other programs, such as excel, and edit the colors, font size, and labels as appropriate for making more visually pleasing figures. When writing a paper, if one of the co-writers wants to match colors from old papers, it is possible to import the old figures, register the color, and then match all future figures for consistency.

Bealls Liste (a backup)

"Beall's List", a creation of Jeffrey Beall, includes criteria for categorizing predatory journals and lists publishers that meet those criteria.

The original list was removed by its creator, however, a copy remains accessible.

Predatory publishers provide limited publishing services while pretending a much higher standard and reputation than they actually have. When publishing in a journal for the first time, ask yourself:

  • Is the journal or publisher listed in Beall's List?
  • If claiming to be an open access journal, is the journal in the DOAJ?
  • Is the publisher a member of recognized professional organizations?
  • Is the journal truly indexed?
  • Is the journal transparent and following best practices in editorial and peer review processes, governance, and ownership?

Information on why Beall's original list disappeared can be found in the web or here.

STRING provides functional protein association networks from information about physical and functional interactions between proteins.

Data from various sources are aggregated using an easy to use web-based interface. After entering a protein name/sequence, a network of different types of interactions (color-coded) is displayed: experimentally verified, based on the genetic context (neighborhood, fusions, co-occurrence), derived from textmining, due to co-expression or based on protein homology.

The network can be recentered on other proteisn, and further information can be displayed for each individual protein (gene names, protein domains, 3D structures, etc.). Links to further databases are provided (e.g. NCBI, KEGG, UniProt, PDB). There are different viewing functionalities across species like neighborhood (adjacent genes of similar proteins) or fusion (identify fusion proteins). The data can be exported in various formats and an API for developers is available. It is even possible to download the raw data that is used by STRING to generate the network; they are provided under a Creative Commons license.

Molecular scenes can be saved in various formats or exported to external rendering tools such as POV-Ray, Tachyon and others.


VOSviewer is a free software tool for constructing and visualizing bibliometric networks.

These networks may for instance include journals, researchers, or individual publications, and they can be constructed based on citation, bibliographic coupling, co-citation, or co-authorship relations. VOSviewer also offers text mining functionality that can be used to construct and visualize co-occurrence networks of important terms extracted from a body of scientific literature.


WolframAlpha introduces a fundamentally new way to get knowledge and answers – not by searching the web, but by doing dynamic computations based on a vast collection of built-in data, algorithms, and methods.

WolframAlpha is based on the software Mathematica. The search engine works particularly well for content from exact sciences and is available also as an app.
