 ## HTAN's h5ad Requirements
 HTAN Centers are encouraged to reference the [sc/snRNA-seq RFC](https://docs.google.com/document/d/1XjDLWulYWhnfZrGCg-0_Jh93ytIp3p_01ZrTyymTjoU/edit?usp=sharing) for additional details. The HTAN h5ad (AnnData 0.10) requirements are modeled after CELLxGENE's requirements.  They also include three attributes developed by the Human Cell Atlas (HCA). Please see the [Background](#background-h5ad-files-cellxgene-human-cell-atlas) section below for more information about h5ad (AnnData 0.10) files, CELLxGENE and the HCA.
