Welcome to ISDB GitHub Page.

Here you will find the full In-Silico MS/MS DataBase (ISDB) described in the paper "Integration of Molecular Networking and In-Silico MS/MS Fragmentation for Natural Products Dereplication". This ISDB contains in-silico predicted MS/MS fragmentation spectra in positive ion mode for 170 602 Natural Products (NPs) from the UNPD (Universal Natural Products Database).

How to use the ISDB ?

Instructions for using this ISDB in a dereplication workflow are available as pdf here (updated on 06/2016): workflow
