This directory contains datasets (deliverable D1) for the IN-CHARGE project with the references to the experimental and theoretical prototype structures. Experimental structures are represented by their COD IDs, theoretical stuctures – by the IDs of the corresponding theoretical structure databases. During 2025 this directory will be periodically updated if new structures are added during the project. After 2025, the directory will be "frozen" at the latest correct Subversion commit in 2025 and will continue to be available as an archive.
