All they had to do was follow along bond for bond with my tutorial video and get the correct answer. The first thing I noticed when looking at the responses is that most of the students got most of the tutorial questions incorrect! I didnвЂ™t understand why. jpg version of the structure so I could check it visually myself if there were any discrepancies. For testing purposes, I also had them upload a. I coded the correct SMILES into the grader вЂ“ as well as some of the common errors for feedback purposes вЂ“ and released it to my students. So I wrote up a pilot quiz with tutorial videos. Perfect! I like the human readable aspect, as students can glance through their SMILES to check for some potential errors. SMILES is a condensed version of the structure, almost human readable, and ChemDraw can copy a structure directly in SMILES format.

And our ChemDraw license does not include the structure-to-name feature. But many of the structures have IUPAC names which can be rather large and/or outside of the scope of IUPAC nomenclature my students learn. So in some respects, IвЂ™m admittedly reinventing the wheel here.ДЄt first I thought the LMS would be able to grade my studentsвЂ™ work if they type in the IUPAC name for each structure. I know some publishers have platforms for just this, but our university doesnвЂ™t subscribe to the service. But what if we wanted to do more? Future articles will offer some ideas.NOT what my exam questions will look likeвЂ¦ Open Babel can read and convert a subset of the ChemDraw CDX file format. Notice how information has been lost (the reaction arrow and text) in this conversion due in part to impedance mismatch between the CDX format and the molfile format. The output is an SD file in which the first molecule is benzene and the second is aniline: benzene-to-aniline-reaction.cdx This generates a properly formatted molfile: benzene.cdxД«abel -icdx benzene-to-aniline-reaction.cdx -omol benzene-to-aniline-reaction.mol If you downloaded the examples, you might use: babel -icdx benzene.cdx -omol benzene.mol Change into the directory containing the CDX files. With a selection of CDX files in hand, we can now convert them. To save even more time, you can download the files I created. In the interest of time and money, I decided to go with Option (3) for now. Free to use with no installation required. It does, however, read CDX files quite nicely.

Unfortunately, the 30-day free trial does not support writing CDX files. Chemdoodle is a full-featured desktop chemical drawing package.

After taking the time to download it, the installer looked sufficiently non-standard on my Mac to make me re-think letting this software loose on my system. I'm not sure if CDX writing is supported in the evaluation version.

I'm running MacPorts, so it was this simple: sudo port install openbabel If you haven't done so already, install Open Babel on your system. In this tutorial, we'll be using the command line utility to read CDX files generated by a drawing program. Open Babel is both a command line utility and a developer toolkit. Given the ubiquity of CDX files, how can we read them in an inexpensive way? This article describes one approach that uses Open Babel. It also described the important role this file format plays in the business and science of chemistry. The previous article in this series gave a brief introduction to the ChemDraw CDX file format.
