+# Dataset Card for Nine-Species excluding Yeast
+Dataset used for the baseline comparison of InstaNovo to other models.
+
+
+## Dataset Description
+
+- **Repository:** [InstaNovo](https://github.com/instadeepai/InstaNovo)
+- **Paper:** [De novo peptide sequencing with InstaNovo: Accurate, database-free peptide identification for large scale proteomics experiments](https://www.biorxiv.org/content/10.1101/2023.08.30.555055v1) 
+
+### Dataset Summary
+
+Dataset used in the original [DeepNovo](https://www.pnas.org/doi/full/10.1073/pnas.1705691114) paper. 
+- The training set contains 8 species excluding yeast
+- The validation/test set contains the yeast species
+
+## Dataset Structure
+
+The dataset is tabular, where each row corresponds to a labelled MS2 spectra.
+- `sequence (string)` \
+  The target peptide sequence excluding post-translational modifications
+- `modified_sequence (string)` \
+  The target peptide sequence including post-translational modifications
+- `precursor_mz (float64)` \
+  The mass-to-charge of the precursor (from MS1)
+- `charge (int64)` \
+  The charge of the precursor (from MS1)
+- `mz_array (list[float64])` \
+  The mass-to-charge values of the MS2 spectrum
+- `mz_array (list[float32])` \
+  The intensity values of the MS2 spectrum
