...In addition to spectral similarity measures, Calibr provides other two types of features related to precursor ion and spectrum property and statistics from spectrum-spectrum matches (SSMs) for machine-learning based validation. To support users to conveniently conduct spectral library searching and validation, we have also implemented a GUI application, called CalibrWizard. It integrates Calibr and PercolatorTsvConverter, a conversion tool for converting Calibr's results into a tab-delimited format as input to Percolator, and can use the function of Percolator for validation. ...
