+# Dataset Card for OG: An Open Genomic Dataset
+
+The OG dataset is a subset of the Open MetaGenomic dataset (OMG).   
+OG contains high quality prokaryotic and viral genomes with taxonomic information, and is roughly 10x smaller than OMG.  
+The dataset is pre-processed into a mixed-modality dataset, with translated amino acids for protein coding sequences, and nucleic acids for intergenic sequences.
+
+Two additional datasets are available on the HuggingFace Hub:
+- [`OMG`](https://huggingface.co/datasets/tattabio/OMG): The full Open Metagenomic dataset with 3.1T base pairs.
+- [`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/OG')
+```
+
+To preview the dataset without downloading, load in streaming mode:
+```python
+import datasets
+ds = datasets.load_dataset('tattabio/OG', streaming=True)['train']
+print(next(iter(ds)))
+```
