Introduction

DiNovo is a software tool for automated, high-coverage and high-confidence de novo peptide sequencing from tandem mass spectrometry data based on multiple pairs of mirror proteases and deep learning technology. It is featured by:

  • Mirror-Spectra Recognition: Fast and accurate recognition of mirror spectral pairs based on a statistical scoring algorithm.
  • De Novo Sequencing: Peptide sequencing from mirror spectral pairs, including MirrorNovo algorithm (deep learning based, running on GPU), and pNovoM2 algorithm (updated version of pNovoM, graph theory based, running on CPU).
  • Quality Control: False discovery rate (FDR) estimation based on target-decoy strategies.
  • High Speed: Whole-process acceleration based on multi-level index system and optimized multiprocess parallel strategy.
  • Easy to Use: Friendly GUI design and optimized command-line interaction.
