CryoET List Annotations

List biological annotations (segmentations, point annotations, surface meshes) for a specific cryo-ET run from the CryoET Data Portal. Annotations label cellular structures such as membranes, ribosomes, and organelles. Returns object name (e.g. 'membrane', 'ribosome'), GO/EMDB ontology ID, annotation method description, count of annotated instances, software used, and metadata paths. Filter by `curator_recommended_only=true` to get curated high-quality annotations.
