Back from Spring08 ACS chemistry

The American Chemical Society meeting in New Orleans proved to be as hectic as usual. I didn't get to spend as much time with everyone I was hoping to touch base with but I did get some useful things done:

1) I presented on the use of Cheminformatics in Open Notebook Science and Teaching Chemistry with Second Life. Since the ACS oral sessions are so short (15-20 mins before questions) this is a good opportunity to get our work recorded in a concise format. Speakers like to complain that they need a full hour to do justice to their elaborate projects but the shorter format seems to match the attention span of most attendees.

2) The Sci-Mix session on Monday was very hectic. I presented two posters related to my talks and helped out with the opening of the poster session on ACS island. We had 20 posters in Second Life and it was great to finally meet a few of the presenters and the organizer Kate Sellar (Finola Graves) in person. Kate was running Second Life on a large screen right at the poster entrance and giving out t-shirts. Andy Lang (Hiro Sheridan) was also helping out remotely from within Second Life. By all accounts it was well received. The posters will remain up on ACS island for the next few months and it will be possible to contact presenters via bells next to their posters.

3) I also finally met several people that I have known only virtually for some time: Rajarshi Guha, David Wild, Rich Apodaca, Noel O'Boyle and Warren DeLano. Rajarshi, Rich, Noel, Warren, Geoff Hutchison and I went out for the Blue Obelisk dinner on Tuesday night.

in XML. He suggested using 4) I had a good brainstorming session with Rajarshi about representing experimental workflowsTaverna to create "null" workflows - since our lab experiments are physical rather than executing code. Noel suggested using Knime. The idea is to represent experimental steps leading to a result in a standard machine readable (and thus minable) format. We're going to start very simply by limiting the workflow space to Ugi reactions.

UsefulChem on ChemSpider chemistry

As Antony Williams mentions in his blog, UsefulChem molecules now have their own url on ChemSpider:

This is important on so many levels. I've been talking about using ChemSpider as an integral part of our research for some time now and we've been steadily migrating content as new functionalities became available. We still have a lot to do to complete the process but the path is clear.

The ability to upload spectra of all types (IR, H NMR, C NMR, MS, etc) in JCAMP-DX format allows for anyone with a browser to drill down to any desired expansion using JSpecView. It just makes sense to upload the NMRs of our starting materials and our fully characterized products so that we can always be just a click away from the online lab notebook when discussing our chemistry.

The value of being able do substructure searching for our compounds is immense. Most organic chemistry students are not interested in learning how to run and maintain software on a lab server to keep track of their molecules. They also don't want to learn SMARTS. ChemSpider has a very familiar graphic interface for drawing molecule fragments to do substructure searching. For a free and hosted solution, the energy of activation for using ChemSpider has become very low indeed, especially for Open Notebook Science applications.

As we approach 200 experiments it is becoming clear that the ability to retrieve information is just as important as doing the experiments. Systematic tagging of experiment pages with InChIKeys and InChIs is a simple way to automatically allow for direct links from ChemSpider to UsefulChem pages via Google.
