Dataset summary

See our preprint for details

Join our slack community for support and discussion about microbiome foundation models.

Each row is one sample. Taxa and Relative Abundances are aligned lists (same length per row): semicolon-separated rank strings for taxa, and matching relative abundances. Additional columns record data type, sequencing method, pipeline version, and study accession.

Data come from processed abundance matrices, filtered, then randomly split into pretrain (90%) and benchmark (10%) with seed=42.

Splits

Split	Description	Num Examples
pretrain	Pretraining subset.	485377
benchmark	Held-out benchmark subset.	53931

Data fields

Column	Type	Description
Taxa	list of string	Taxon labels.
Relative Abundances	list of float	Relative abundances in the same order as Taxa.
Sample	string	Sample identifier, if present.
Data Type, Sequencing Method, Pipeline Version, Study Accession	string	Provenance metadata; exact set of columns matches the published Parquet schema.

Filtering

Filtering used:

• min_relative_abundance: 0.0001
• min_num_taxa: 10

Usage

This repository is gated. To use it you'll need to:

1. Request access — click the "Request access" button at the top of this repo's page on Hugging Face. Requests are auto-approved.
2. Authenticate — log in to Hugging Face from your environment so the download tooling can use your token:

   huggingface-cli login

Or set the token directly:

   export HF_TOKEN=hf_xxxxxxxxxxxxxxxxxxxx

You can create a token at https://huggingface.co/settings/tokens.

Once both steps are done, you can load the model/dataset normally:

from datasets import load_dataset

ds = load_dataset("outpost-bio/Atlas")
row = ds["pretrain"][0]
taxa = row["Taxa"]
abund = row["Relative Abundances"]
