Here we present Matcher, an application with novel techniques for searching and visualizing MMP data generated by unsupervised MMP identification. Matcher is built around the popular mmpdb platform, an open-source python library that uses the 'fragment-and-index' algorithm pioneered by Hussain and Rea 5 for unsupervised MMP database generation. Matcher includes the following key innovations beyond previous platforms for MMP analysis, including mmpdb.
