⚠️ Note: This table is a non-exhaustive quick-reference. Companion and index files (.bai, .csi, .tbi, .crai) that enable interpretation or reconstruction of underlying controlled-access genomic data are also subject to controlled-access deposition requirements. For ambiguous cases, consult your NIH Genomic Program Administrator (GPA) before depositing.
