DART-Eval: A Comprehensive DNA Language Model Evaluation Benchmark on Regulatory DNA

The Dart-Eval preprint is available here: (Insert Preprint Link)

Data

All data is available for download at Synapse project syn59522070.

Tasks

The commands in this section reproduce the results for each task in the paper. The output files mirror the structure of the Synapse project.

Preliminaries

Prior to running analyses, set the $DART_WORK_DIR environment variable. This directory will be used to store intermediate files and results.

Additionally, download the genome reference files from syn60581044 into $DART_WORK_DIR/refs, keeping the file names. These genome references are used across all tasks.

In the following commands, $MODEL represents the evaluated DNALM architecture, one of dnabert2, gena_lm, hyenadna, and nucleotide_transformer. $MODEL_SPECIFIC_NAME represents the specific version of each model, namely one of DNABERT-2-117M, gena-lm-bert-large-t2t, hyenadna-large-1m-seqlen-hf, and nucleotide-transformer-v2-500m-multi-species .

Task 1: Prioritizing Known Regulatory Elements

All inputs, intermediate files, and outputs for this task are available for download at syn60581046.

Inputs

This task utilizes the set of ENCODE v3 candidate cis-regulatory elements (cCREs). A BED-format file of cCRE genomic coordinates is available at syn62153306. This file should be downloaded to $DART_WORK_DIR/task_1_ccre/input_data/ENCFF420VPZ.bed.

Dataset Generation

python -m dnalm_bench.task_1_paired_control.dataset_generators.encode_ccre --ccre_bed $DART_WORK_DIR/task_1_ccre/input_data/ENCFF420VPZ.bed --output_file $DART_WORK_DIR/task_1_ccre/processed_inputs/ENCFF420VPZ_processed.tsv

This script expands each element to 350 bp, centered on the midpoint of the element. The output file is a TSV with the following columns:

chrom: chromosome
input_start: start position of the length-expanded element
input_end: end position of the length-expanded element
ccre_start: start position of the original cCRE
ccre_end: end position of the original cCRE
ccre_relative_start: start position of the original cCRE relative to the length-expanded element
ccre_relative_end: end position of the original cCRE relative to the length-expanded element
reverse_complement: 1 if the element is reverse complemented, 0 otherwise

Task 3: Discriminating Cell-Type-Specific Elements

All inputs, intermediate files, and outputs for this task are available for download at syn60581042.

Inputs

This task utilizes ATAC-Seq experimental readouts from five cell lines. Input files are available at syn60581166. This directory should be cloned to $DART_WORK_DIR/task_3_peak_classification/input_data.

Dataset Generation

Using the input peaks from ENCODE, generate a consensus peakset:

python -m dnalm_bench.task_2_5_single.dataset_generators.peak_classification.make_consensus_peakset

Then, generate individual counts matrices for each sample, using input BAM files from ENCODE and the consensus peakset:

python -m dnalm_bench.task_2_5_single.dataset_generators.peak_classification.generate_indl_counts_matrix GM12878 $BAM_FILE

python -m dnalm_bench.task_2_5_single.dataset_generators.peak_classification.generate_indl_counts_matrix H1ESC $BAM_FILE

python -m dnalm_bench.task_2_5_single.dataset_generators.peak_classification.generate_indl_counts_matrix HEPG2 $BAM_FILE

python -m dnalm_bench.task_2_5_single.dataset_generators.peak_classification.generate_indl_counts_matrix IMR90 $BAM_FILE

python -m dnalm_bench.task_2_5_single.dataset_generators.peak_classification.generate_indl_counts_matrix K562 $BAM_FILE

Concatenate the counts matrices and generate DESeq inputs:

python -m dnalm_bench.task_2_5_single.dataset_generators.peak_classification.generate_merged_counts_matrix

Finally, run DESeq for each cell type to obtain differentially accessible peaks for each cell type:

Rscript dnalm_bench.task_2_5_single.dataset_generators.peak_classification.DESeqAtac.R

The final output consists of the differentially accessible peaks, available at syn61788656.

Zero-shot baseline clustering

Use FIMO to generate motif scores for each peak sequence.

The following notebook contains information on how to produce the zero-shot clustering results, using the motif counts from FIMO:
