Inspired by the success reported in my last blog post [Link] about the open source docking program rDock [http://rdock.sourceforge.net], I decided to investigate the docking accuracy performance of rDock more in depth. Once upon a time in the west the commercial docking program GOLD was benchmarked with two ...

Last time i tested the basics of the docking program rDock; Installation, basic setup and docking, as well as had a brief walkthrough about how to post-process the results with the rDock SD file utilities. However, as I've covered before, you should never use re-docking as an estimation of ...

rDock is an open source docking program, trying to solve the same kind of scientific questions as Autodock Vina, which I have covered in a couple of earlier blogposts. It was open sourced in 2012, but development of the earliest versions dates back to 1998. More details can be ...

During the summer holidays I gave a presentation with the title "Open Drug Discovery" at the Gifted Children summer camp 2016. The presentation covered drug discovery and open innovation in drug discovery research, with a focus on what possibilities amateurs have to contribute. Gifted Children is an association for gifted children and their parents. Gifted children advocates a better understanding and ...

Sometimes it comes in handy to be able to note a date or time quickly in Excel. This happens often when using Excel sheets for logging purposes and registration of laboratory experiments and results. This post illustrates how to make a drop-down with todays date where the entered date will not update automatically. Data validation for drop-down menus For this purpose the ...

In the two previous blog posts Ligand docking with Smina and Never use re-docking for ..., it was demonstrated how easy it is to dock a small ligand using Smina, and how deceptively accurate a docking program can be when using re-docking rather that cross-docking. It is however possible to re-tune the docking function to a specific purpose using machine ...

Re-docking of ligands found in PDB files are often used as a fast evaluation of a docking program before working with designed or other ligands. However this re-docking can give deceptively good results and it is recommended to instead test with cross docking. In this follow up blog post I give a short example of how it can be done. Cross ...

Moleculer Docking is a powerful technique for studying potential ligand-receptor interactions. It can be done with free tools. In this blog post I showcase the docking program Smina, a fork of Autodock Vina. Automated docking is the process of prediction of how one molecule binds to another in ...

When I have been working with chemical databases and import of molecules I have encountered numerous problems with the way chemical structures are drawn. Most often the problem arises as creative users in the past have had a problem with registering a compound the way they wanted it. Sometimes the used ...

Toxic compounds are most often something that we try to avoid when designing novel pharmaceutical compounds, so it could be nice to get a prediction if a compound is toxic even before ressources are used to synthesize it.  But what if it comes back as predicted ...
