+# `Mouse_DNA_v0`
+
+## Dataset Description
+
+The `davidcechak/Mouse_DNA_v0` is a dataset containing raw DNA sequences from the mouse reference genome (*Mus musculus*). It is intended as a foundational dataset for various machine learning and bioinformatics tasks, such as training models to recognize patterns in mouse DNA.
+
+As a foundational dataset, it can be used directly for research or further processed into different formats, such as the 6-mer tokenized version, `davidcechak/Mouse_DNA_v0_DNABert6tokenized`. This allows for flexibility in using different model architectures, including those based on transformers like DNABert.
+
+## Dataset Structure
+
+The dataset is available in the `parquet` format and is likely split into training and testing subsets, though this needs to be confirmed.
+
+### Data Fields
+
+The dataset likely includes the following fields:
+*   **text**: A raw DNA sequence string, consisting of the nucleotides `A`, `T`, `C`, and `G`.
+
+## Dataset Creation
+
+### Data Source
+
+The raw DNA sequences are likely derived from the reference genome of *Mus musculus*.
+
+### Preprocessing and Format
+
+The raw genomic sequences were extracted and formatted into `parquet` files, which are efficient for large-scale data processing in machine learning workflows.
+
+## Intended Uses
+
+The dataset can be used for:
+*   **Bioinformatics Research**: Exploring the applications of machine learning to analyze raw mouse genomic data.
+*   **Genomic Classification**: Building models to identify specific features within mouse DNA.
+*   **Comparative Genomics**: Comparing genomic features between different species (e.g., mouse, human, worm) by using this dataset alongside similar ones.
+
+## Limitations and Ethical Considerations
+
+*   **Unspecified Origin**: Without an official dataset card from the author, the precise origin and collection methodology of the sequences are unknown. This may impact reproducibility and potential biases.
+*   **Licensing**: The license is currently unspecified. For any public or commercial use, it is necessary to verify the terms with the author, David Cechak, on Hugging Face.
+
+## How to Get the Dataset
+
+You can easily load this dataset from the Hugging Face Hub using the `datasets` library:
+
+```python
+from datasets import load_dataset
+
+# Load the dataset
+dataset = load_dataset("davidcechak/Mouse_DNA_v0")
+
+# Access the training split
+train_dataset = dataset["train"]
