0-indexing. 1-indexing. The quite different matter of atom indexing. Put all of these together and one might quite well go mad. #chemoinformatics #chemchat

No idea why I used to hate fluorine so much when I was in the lab, any more. Hydrogen is easily the worst element. Worst ever. #chemoinformatics

Who knew, when first starting a chemistry degree, that the humble hydrogen atom would give you more trouble than all the rest put together, yes, even the metals 😂 #chemoinformatics #chemistsWhoCode #chemchat

Any #SMARTS wizards out there? How would I write a SMARTS pattern for, say, an OH group and a chlorine attached anywhere to the same aromatic ring?

EDIT: I figured it out!

If you're looking for resources to teach #machineLearning and some of its applications to #genomics or #chemoinformatics: I post most of my teaching materials on my website https://cazencott.info/index.php/pages/Teaching and they are available under a CC-BY license if you want to reuse them.

I consider it part of my job as a public servant to make what I create publicly available, but not everyone shares this take...

New blog post about my journey with the editors-in-chief of the Journal of Cheminformatics (@rguha and @[email protected]) to pilot a reproducibility review as part of submission.

We’re excited to be starting the next phase of {volcalc} 📦 development in collaboration with Dr. Laura Meredith with funding from @RConsortium. {volcalc} is a WIP #rstats package for calculating estimated volatility of chemicals.

I spent some time today learning to read/write SMILES and SMARTS and although my brain hurts a bit, it's actually not *that* tough. SMARTS is like regular expressions, but for molecules. Like regex, it gets tricky when you need something very specific (e.g OH groups not on an aromatic ring; phenols but not nitrophenols). I wish there was a SMARTS equivalent of this interactive regex explorer: https://regex101.com/

{webchem} 1.3.0 is released on CRAN! This version brings some new features to nist_ri() 🎉 and sadly deprecates some functions whose corresponding APIs no longer exist 💀. Read the full changelog here: https://docs.ropensci.org/webchem/news/index.html#webchem-130

🎉 Just got notice that we got funding from the R Consortium to work on a really interesting project! `volcalc` is an R package for calculating estimated volatility of chemicals. Currently only works for compounds in the KEGG database, but we're going to re-factor so it works on any SMILES, InChI, or .mol file representation. I'm super excited to work on this!

Hi everyone. I am a chemoinformatician who just jumped ship from Twitter. I hope we can recreate here what made Twitter so good sharing science. #introduction #chemoinformatics
