A few days ago I had made available a SMARTS version of the PAINS substructural filters, that were converted using CACTVS from the original SLN patterns. I had mentioned that the SMARTSViewer application was a handy way to visualize the complex SMARTS patterns. Matthias Rarey let me know that his student had converted all the […]
Recent versions of rcdk allow you to insert images of chemical structures into R plots, via the view.image.2d and rasterImage functions. One problem with the latter function is that the 2D structure image must be located in plot units, rather than pixel units. Paul Murrell suggested an easy way to insert the raster image into […]
In preparation for the upcoming R workshop at the EBI, I’ve been cleaning up the rcdk package and updating some features. One of the new features is the ability to get a 2D depiction as a raster image. Uptil now, 2D depictions were drawn in a Swing window – this allowed you to resize the […]
The folks at the EBI have been doing some great work on the CDK. A major effort is underway to revamp JChemPaint and part of this involves improving the rendering of 2D depictions. While not complete I rebuilt a version of the CDK 1.2.x branch with the latest rendering code from the jchempaint-primary branch and […]
Sometime back I was playing around with dynamic HTML and cam across a tutorial that described how to implement the dynamic suggestion feature that is commonly found on many websites (such as Google and Amazon). This set me wondering how I could use this mechanism to dynamically depict a SMILES string as I type it.
