CRISPR-Cas Atlas – GENERator-ready Dataset

This dataset is a derived, preprocessed version of the CRISPR-Cas Atlas, formatted for causal language model fine-tuning with GENERator.

Source

Original dataset:
CRISPR-Cas Atlas v1.0

Ruffolo et al., Design of highly functional genome editors by modeling the universe of CRISPR-Cas sequences, bioRxiv (2024)
https://www.biorxiv.org/content/10.1101/2024.04.22.590591v1

Processing

Each CRISPR-Cas operon was converted into a single DNA sequence by concatenating:

1. CRISPR repeat
2. CRISPR spacers
3. tracrRNA (RNA converted to DNA via U→T)

All sequences:

• Contain only A/C/G/T
• Are left-padded with A to ensure the sequence length is a multiple of 6
• Are compatible with GENERator’s 6-mer tokenizer
• Are suitable for causal language model fine-tuning

Dataset Format

Each line in the JSONL file contains a single field:

{ "sequence": "ACGTACGT..." }
