OAS95-aligned-cleaned
A cleaned and IMGT-aligned antibody sequence dataset derived from the Observed Antibody Space (OAS) database.
Preparation
- Started from the OAS dataset preprocessed with the IgLM pipeline and clustered at 95% sequence identity.
- Numbered all sequences with ANARCII using the IMGT numbering scheme.
- Removed heavy- and light-chain sequences with numbering gaps at the first framework position.
- Removed light-chain sequences shorter than 90 residues.
- Retained 203,968,932 training sequences and 11,819,793 test sequences across 6 organism labels and 2 chain types.
