# CodonTranslator Data
This repository contains the final public training-data release used for CodonTranslator.
## Contents
- `train/`: representative-only training shards
- `val/`: representative-only validation shards
- `test/`: representative-only held-out test shards
- `embeddings_v2/`: precomputed species conditioning embeddings used in training
- `_work/final_representative_counts.json`: final released split sizes
- `_work/split_report.json`: split audit report
- `_work/mmseqs_manifest.json`: MMseqs version and clustering parameters
- `_work/cluster_split.parquet`: cluster-level split assignments
- `_work/seq_cluster.parquet`: MMseqs cluster assignments
- `_work/seq_split.parquet`: split assignments before representative selection
## Split definition
The public `data_v3` split was rebuilt from `data_v2` with the following rules:
- MMseqs clustering in **protein space**
- test holdout by **binomial species**
- validation split from **seen species but unseen clusters**
- representative-only parquet outputs, one retained row per released representative sequence
Mixed seen/held-out protein clusters and exact-protein leakage cases are removed on the seen side before final release.
## Final released split sizes
- `train = 36,888,301`
- `val = 373,637`
- `test = 331,455`
All three released splits satisfy:
- exact protein overlap `train/val = 0`
- exact protein overlap `train/test = 0`
- test species not seen in train/val
- representatives-only rows, so `rows == unique_seq_id`
## Parquet schema
Each released parquet shard contains these columns:
- `RefseqID`
- `protein_refseq_id`
- `protein_seq`
- `cds_DNA`
- `taxon`
- `shard`
## Embeddings
`embeddings_v2/` is the exact species embedding store used in training. It contains:
- `species_vocab.json`
- `species_index.json`
- `species_tok_emb.bin`
- `metadata.json`
- `taxonomy_database.json`
The released `data_v3` taxa are fully covered by this embedding store.
## Model and code
The corresponding public model and code release is:
- `alegendaryfish/CodonTranslator`
## Attribution
This release redistributes processed training data and derived embeddings for reproducibility of the CodonTranslator experiments. See the audit files in `_work/` for construction details and final verification outputs.
The raw MMseqs working database is not included because it is large, machine-specific intermediate state. The released `_work/` files are the reproducibility artifacts needed to audit and reconstruct the clustering and split decisions.
