IUPAC 化学标识符软件 InChI 非常可靠。它已经在世界各地的大型数据库上进行了测试,并证明自己是处理和集成大型化学数据库的重要工具。 InChI 版本 1.05 于 2017 年 1 月发布,版本 1.06 于 2020 年 12 月发布。在本文中,我们报告了 InChI 软件的当前状态、v1.06 版本中的改进细节,以及 InChI 在 PubChem(包含超过一亿个分子的数据库)上运行的测试结果。此次升级引入了重要的新功能,包括对伪元素原子的支持和改进的聚合物描述。我们预计使用标准 InChI 的应用程序很少(如果有的话)需要因版本 1.06 中的更改而进行更改。该数据库的 0.002% 被发现存在数值不稳定,并且发现了少数其他分子,算法运行不顺畅。根据 PubChem 数据,我们可以证明 InChI 1.05 版本的准确度为 99.996%,而 InChI 1.06 版本则更接近完美。最后,我们期待 InChI 化学标识符的未来版本和扩展。
The software for the IUPAC Chemical Identifier, InChI, is extraordinarily reliable. It has been tested on large databases around the world, and has proved itself to be an essential tool in the handling and integration of large chemical databases. InChI version 1.05 was released in January 2017 and version 1.06 in December 2020. In this paper, we report on the current state of the InChI Software, the details of the improvements in the v1.06 release, and the results of a test of the InChI run on PubChem, a database of more than a hundred million molecules. The upgrade introduces significant new features, including support for pseudo-element atoms and an improved description of polymers. We expect that few, if any, applications using the standard InChI will need to change as a result of the changes in version 1.06. Numerical instability was discovered for 0.002% of this database, and a small number of other molecules were discovered for which the algorithm did not run smoothly. On the basis of PubChem data, we can demonstrate that InChI version 1.05 was 99.996% accurate, and InChI version 1.06 represents a step closer to perfection. Finally, we look forward to future releases and extensions for the InChI Chemical identifier.
