Analysis method

Number antibody variable domains

Apply a consistent antibody numbering scheme, label framework and CDR residues, and keep the annotations with the source Dataset.

Method details

Input checks

  • Unambiguous protein sequence in the selected column
  • One frozen Selection or Dataset Version
  • Up to 1,000 rows and 500 residues per row

Expected results

  • Numbered residues — Review canonical antibody positions alongside the source residues.
  • Framework and CDR labels — Separate framework and complementarity-determining regions.
  • Row-level quality summary — Review the numbering scheme, processing status, and any sequence validation issues.
