  "table_description": "This table contains metadata about the Microscopy Bulk Simple Annotations (ANN) series available in IDC. Each row corresponds to a DICOM series containing annotations, and includes attributes such as the annotation coordinate type and references to the annotated image series. For detailed group-level information (counts, graphic types, property codes), join with ann_group_index using SeriesInstanceUID. This table can be joined with the main idc_index table using the SeriesInstanceUID column. Note: ANN series are assumed to contain a single instance.",
