hansen7/spatialagent_human huggingface dataset:
Expert 7
Cell-type annotation workflow: Leiden clustering with manual annotation using marker gene sets and DEG (per Scanpy tutorial); projected cell types spatially; used spatial position and key marker expression for final annotation; provided 3-tier annotation.
Tissue-niche annotation workflow: Used UTAG for spatial clustering; labeled structures based on position and anatomical knowledge of heart (e.g. 'chamber wall is thicker on the left ventricle').
