Linking files through depositor defined IDs

While more basic data can be described using compound, assay and reference IDs (CIDX, AIDX and RIDX), additional identifiers are required to link more complex data, shown in the table below:

*IDX	Description	Primary File
ACT_ID	ACTivity ID	ACTIVITY
TEOID	TEst Occasion ID	ACTIVITY
REGID	REcord Grouping ID	ACTIVITY_SUPP
SAMID	Supplementary Activity Mapping ID	ACTIVITY_SUPP

Identifiers present in the files link data at different levels
