Latest Release of New STN® Extends Export to Excel®  Support to 28 More Databases

Closely following the introduction of Export to Excel support for CAplusSM and DWPISM in July, the October release of New STN extends Excel support to an additional 28 databases, further facilitating workflow integration and analysis of new STN search results.

The latest release also enhances structure drawing and query precision with the addition of deuterium and tritium atoms to the structure editor Common Atoms palette and superatom support for DCR. Other recent structure search improvements for the Derwent Markush Resource (DWPIM), DCR and REAXYSFILESub include better search performance, as well as increased precision of closed substructure searches, element count, atom lock, ring lock and matching.

For more details about the release, please view a recorded What's New presentation. A number of additional informational resources, including Quick Start Tutorials, are available on the STN training webpage and within new STN.
