Dear Orbitrap users,
We are running a new series of webinars to familiarize our user-base with more functions in Thermo Fisher Scientific™ Compound Discoverer™ software.
The sessions will vary in topics and suitability to your level of experience. You are welcome to register, and forward to your colleagues, in any or all of the sessions below.
Each session is described briefly here and in detail in the registration link. You may directly register via the link provided for each session. You need to fill a short registration form for each session, but you can save your answers and spare a few clicks if you intend to register for more than one session.
The series will be presented by Elizabeth Crawford, Vincent Jespers and Anas Kamleh.
QuickFix 1 for Compound Discoverer 3.2 is now available for download : https://thermo.flexnetoperations.com/control/thmo/product?plneID=820507 .
It primarily fixes the problem with invalid structures in the Natural Products Atlas Mass List, which sometimes caused a “Cannot create structure from given MOL string” error. We also made a small change in the Mass List Editor to make sure we don’t see this problem again with other mass lists.

Compound Discoverer is an integrated software platform to handle all your metabolomics data analysis needs including statistics for comparative analysis, unknown annotations, data visualization, pathway mapping, and stable isotope labeling. In this presentation, we will discuss some of the challenges in metabolomics data analysis and take a closer look at the unique tools and flexible workflows in Compound Discoverer that help streamline the data analysis and get results faster. This presentation also includes a preview of the new features in the upcoming version 3.2.
A couple new scripting nodes can be found here.
- Adding an m/z column to the Compounds table
- Adding m/z and Delta Mass [ppm] columns to the Expected Compounds table
- Calculate O/C and H/C ratios in the Compounds table
- Show KEGG IDs (top mzCloud hit) in the Compounds table
Your feedback and requests for additional scripting nodes are welcome!
We appreciate that many people are transitioning to working from home and would like to do what we can to ease that transition. We realize that you may need access to data processing software, which is currently licensed on a lab-based computer. We would like to remind you that you can download fully functioning versions of our software from http://thermo.flexnetoperations.com to load on a remote-based computer. You will get an automatic 60-day trial license (no license key needed), which we will extend as needed during this challenging period. To extend a license, please send an email to ThermoMSLicensing@thermofisher.com.
