DLCoalSim-10Mb-v1

DLCoalSim-10Mb-v1 is a 10 Mb simulated haplotype dataset for demographic history inference and Ne(t) prediction.

This repository is for data hosting only. Simulator code, loaders, validation tools, benchmark code, and the future index website are hosted outside this dataset repository.

Current contents:

22,304 samples
697 data shards
10,000,000 bp per sample
64 haplotypes per sample
64 target time bins
17.94 GiB of shard files

The dataset stores minimally processed observations:

bit-packed haplotypes
sparse missing-genotype indices
variant positions
observed recombination and mutation maps
bin-averaged target log10 Ne(t)
per-sample metadata

Shard Schema

Each shard in samples/*.npz contains ragged arrays encoded with offset arrays:

sample_id
target_log10_ne
variant_positions_bp, variant_offsets
genotype_packed, packed_hap_bytes, n_haplotypes
missing_flat_idx, missing_offsets
sequence_length
obs_rec_pos, obs_rec_pos_offsets, obs_rec_rate, obs_rec_rate_offsets
obs_mut_pos, obs_mut_pos_offsets, obs_mut_rate, obs_mut_rate_offsets

Each shard has a matching samples/*.jsonl.gz file with full per-sample metadata in the same order as sample_id.
