"table_description": "This table contains detailed metadata about individual annotation groups within Microscopy Bulk Simple Annotations (ANN) series in IDC. Each row corresponds to a single annotation group, providing granular information about the graphic type, number of annotations, property codes, and algorithm details. This table can be joined with ann_index using SeriesInstanceUID for series-level context. Note: ANN series are assumed to contain a single instance.",
