Bond Artifacts in SketchEl2, and round-trip MDL Molfile

wmk_artifacts01Awhile back I described the idea of bond artifacts, which are layered on top of a core cheminformatics representation to give the rendering engine the hints it needs to make the visual diagram look like what chemists want to see (without breaking the underlying machine readability). Now this enhancement has been added to the open source WebMolKit framework and the derived SketchEl2 drawing app. Furthermore, the artifacts can survive a round trip encoding with the industry standard Molfile CTAB format.

Adventures with combining PubMed and ChEMBL

One of the things I’ve been investigating lately is the open access segment of PubMed, which is a rather massive collection of open access medicine-relevant publications, with accompanying full text.  Similarly with the ChEMBL database, which is focused on structure-activity data traceable back to the original literature document from which each datapoint was curated. This is all for the purpose of advancing the BioAssay Express mission of making the world’s bioassay protocols machine readable (aka FAIR). Continue reading
