GNPS Office Hours

We are hosting online office hours on a weekly basis online with Ming (, Lab Website) via Zoom:

In office hours we'll cover new and old features of GNPS and most importantly we'll take your personal questions about GNPS, computational mass spectrometry, and any science you want to chat about! We'll start office hours given the time below and keep going until there are no more questions. If office hours get too busy, we will limit each question to 10 min.
