We provide a tool to automatically create tautomers. You can use it by accessing "create tautomers" in the "Tools" menu bar. Prof. Kitaura gave us valuable advices to prepare for the tool. In addition, he is helping and encouraging us through the PCCDB project. We deeply appreciate those.
We recently found a (Japanese) blog article to introduce PCCDB, where usages are briefly summarized. We note that the article provides the Google translation service, and so we can read it in English. At the blog site (PC CHEM BSSICS.COM), other various computational tools to use quantum chemistry methods are introduced in an easy-to-understand manner. You can find an article for the PubChemQC project.
Now, we can visualize molecular orbitals and electrostatic potential. Those can be accessed from a "View mol" page for detailed information of an individual molecule.
We will introduce the PCCDB project in the "11th Annual meeting of Japan Society for Molecular Science 2017" in Sendai. The presentations will be held in Japanese. Nakata Maho and Tomomi Shimazaki will be present on 3F07 on 9/17 and 4F06 on 9/18, respectively.
We provide a web service for searching molecules from your CSV files, as "search from CSV" in Tools. We hope it will help you to manage and create your own molecular database, although it's simple. In addition, we start several simple services, such as "mol viewer", "view mol from SMILES", and "convert to 2D mol". (We made a minor update for "convert to 3D mol").
Our paper, "PubChemQC Project: A Large-Scale First-Principles Electronic Structure Database for Data-Driven Chemistry", is published in J. Chem. Inf. Model.To journal site
