Based on the contents of the `README.md` and `DATASET_SUBMISSION.md` files, here are the identified issues:

1. **Issue: Missing task configuration file**
    - **Evidence**: "A task configuration file that stores an available task on the given dataset. See [GLI Task Format](./FORMAT.md#gli-task-format)."
    - **Description**: According to the `DATASET_SUBMISSION.md` guidelines, each dataset submission must include a task configuration file (e.g., `task_<task_type>.json`). The `README.md` file references a Jupyter notebook for preprocessing but does not mention any task configuration file, indicating that it is missing from the dataset submission.

2. **Issue: Incomplete description in README.md**
    - **Evidence**: "Check MUTAG.ipynb for the preprocessing."
    - **Description**: The `README.md` file mentions checking `MUTAG.ipynb` for preprocessing details but does not provide a summary or any description of the preprocessing steps within the `README.md` itself. Including a brief description of the preprocessing steps in the `README.md` would provide more context and make the documentation more complete.

3. **Issue: Inconsistent citation format**
    - **Evidence**: 
      ```markdown
      `@article{Debnath1991StructureactivityRO,
        title={Structure-activity relationship of mutagenic aromatic and heteroaromatic nitro compounds. Correlation with molecular orbital energies and hydrophobicity.},
        author={Asim Kumar Debnath and R L Compadre and Gargi Debnath and Alan J. Shusterman and Corwin Hansch},
        journal={Journal of medicinal chemistry},
        year={1991},
        volume={34 2},
        pages={
          786-97
        },
        url={https://api.semanticscholar.org/CorpusID:19990980}`
      ```
    - **Description**: The citation in the `README.md` uses backticks for formatting. This could lead to formatting issues when rendered. Instead, the citation should use standard Markdown or plain text to ensure consistency and readability.

These issues should be addressed to ensure the dataset submission aligns with the guidelines provided in `DATASET_SUBMISSION.md` and that the documentation is complete and consistent.
