Dataset Card for High-Confidence ProteomeTools

Dataset used to train, validate and test InstaNovo and InstaNovo+.

Dataset Description

Repository: InstaNovo
Paper: De novo peptide sequencing with InstaNovo: Accurate, database-free peptide identification for large scale proteomics experiments

Dataset Summary

This dataset consists of the highest-confidence peptide-spectral matches from three parts of the ProteomeTools datasets. The original datasets may be found in the PRIDE repository with identifiers:

PXD004732 (Part I)
PXD010595 (Part II)
PXD021013 (Part III)

The dataset has been split on unique peptides with the following ratio:

80% train
10% validation
10% test

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

MaxQuant additional columns:

experiment_name (string)
evidence_index (in64)
scan_number (in64)
precursor_recalibrated_mz (float64)
