# Kūkulu Training Data - Prepared and Masked PDB Structures of Antibody-Antigen Complexes

This dataset contains cleaned antibody-antigen complex structures for AI model training. This including two versions of various PDBs:

- **Prepared:** Antibody-antigen complex structures prepared for consistency.
  - Heavy and light antibody chains, trimmed to the Fv portion.
  - Removed non-antigen chains (heterogens, waters, and protein chains not part of the complex).
    
- **Masked:** The same as the prepared structure, but with the CDR loops removed.
