Dorado-Bench v2 - ONT Basecalling
Basecalling toolkit for UM HPC clusters with provenance tracking.
Integration
Run through ont-experiments for provenance tracking:
ont_experiments.py run basecalling exp-abc123 --model sup --output calls.bam --json stats.json
Or standalone:
python3 dorado_basecall.py /path/to/pod5 --model sup --cluster armis2 --output calls.bam

Options
| Option | Description |
|---|---|
--model TIER |
fast, hac, sup (default: hac) |
--version VER |
Model version (default: v5.0.0) |
--cluster |
armis2 or greatlakes |
--output FILE |
Output BAM file |
--json FILE |
Output JSON statistics |
--slurm FILE |
Generate SLURM script |

SLURM Generation
python3 dorado_basecall.py /path/to/pod5 \
--model sup@v5.0.0 \
--cluster armis2 \
--slurm job.sbatch
sbatch job.sbatch
Event Tracking
When run through ont-experiments, captures:
- Model name and full path
- Model tier/version/chemistry
- Batch size and device
- BAM statistics (reads, qscore, N50)
- SLURM job ID, nodes, GPUs
Methylation Calling
ont_experiments.py run basecalling exp-abc123 \
--model sup \
--modifications 5mCG_5hmCG \
--output calls_5mc.bam
Resources adjusted: memory +50%, batch size -30%
