# CIDX ## CIDX Requirements * Depositor-defined Compound IDs (CIDXs) are defined in COMPOUND\_RECORD deposition files. * The CIDX string should be meaningful to the depositor, for example the identifier, name or abbreviations used in the deposition. #### Suggested format: Smith\_KinaseXYZ\_compound12b\ (abbreviation of the group leader, subject area, specific identifier). This CIDX is easy to differentiate from others, and easy to track through the deposition files. It makes any data issues during loading easier to resolve, and makes your data easier to search when loaded. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
