Carbon Perturbation Bench

Two sequence-level perturbation tasks for evaluating DNA foundation models:

  • tata (5,000 rows): the TATA-box motif inside a real promoter is disrupted with random nucleotide substitutions. Probes whether the model has internalised eukaryotic promoter architecture (it should assign higher log-likelihood to the intact promoter than the perturbed one).
  • synonymous_codons (5,000 rows): codons in a real CDS are replaced with synonyms encoding the same amino acid. Probes whether the model has learned codon-usage bias (it should prefer native codon usage over the synonymous variant).

Both subsets share the same schema:

column description
chr, start, end, strand hg38 locus
length sequence length in bp
original_sequence the real (unperturbed) sequence — positive
sequence the perturbed sequence — negative control

Usage

from datasets import load_dataset

tata = load_dataset("hf-carbon/carbon-perturbation-bench", "tata", split="train")
syn = load_dataset("hf-carbon/carbon-perturbation-bench", "synonymous_codons", split="train")

Eval recipe

Pairwise likelihood discrimination: score LL(original_sequence) vs LL(sequence) under the model, and report mean(LL(real) >= LL(perturbed)). A ready-to-run scorer for Carbon, GENERator, and Evo2 lives at evaluation/perturbation_tasks.py in the Carbon release repo.
