+# Dataset Card for OMG: An Open MetaGenomic Dataset
+
+The OMG is a 3.1T base pair metagenomic pretraining dataset, combining EMBL's MGnify and JGI's IMG databases. The combined data is pre-processed into a mixed-modality dataset, with translated amino acids for protein coding sequences, and nucleic acids for intergenic sequences.
+
+We make two additional datasets available on the HuggingFace Hub:
+- [`OG`](https://huggingface.co/datasets/tattabio/OG): A subset of OMG consisting of high quality genomes with taxonomic information.
+- [`OMG_prot50`](https://huggingface.co/datasets/tattabio/OMG_prot50): A protein-only dataset generated by clustering OMG at 50% sequence identity, resulting in 207M protein sequences.
+
+See [https://github.com/TattaBio/OMG](https://github.com/TattaBio/OMG) for details and example tokenization script. 
+
+## Use
+
+```python
+import datasets
+
+ds = datasets.load_dataset('tattabio/OMG')
+```
+
+To preview the dataset without downloading, load in streaming mode:
+```python
+import datasets
+
+ds = datasets.load_dataset('tattabio/OMG', streaming=True)['train']
+print(next(iter(ds)))
+```
