+experiments, for example, from CITE-seq or 10X Visium technologies.  It holds
+all molecular information and associated metadata, including (for example)
+nearest-neighbor graphs, dimensional reduction information, spatial
+coordinates and image data, and cluster labels.  This package also supports
+rapid and on-disk conversion between h5Seurat and AnnData objects, with the
+goal of enhancing interoperability between Seurat and Scanpy.")
