Compound Discoverer can display KEGG IDs or Compound Class as an additional column in the “Compounds” table for all compounds with hits in mzCloud™. To ensure desired IDs are displayed in your Compounds table, please edit the parameters of the “Assign Compound Annotation” node and select KEGG ID or Compound Class in the dropdown menu for the mzCloud Search.

BioCyc has recently gained popularity as an excellent pathway mapping tool. The database accommodates metabolic networks for ~ 20,000 sequenced organisms across 3,105 pathways, and ~ 19,000 metabolites. Its superior informatics functions allow zoomable pathway diagrams featuring chemical structures and offer the key capability of overlaying user-obtained OMICS study results (e.g., fold change, peak area, or stable isotope labeling data) onto organism-specific metabolic pathways, producing data-oriented pathway representation and leading the way to successful biological interpretations.

Many academic organizations have institutional subscriptions https://biocyc.org/subscriber-list.shtml  and BioCyc offers a free trial period for all Thermo Fisher Scientific users as well as a 20% discount for a one-year subscription. For more information, please visit https://biocyc.org/thermofisher.shtml

Attached is a tutorial showing you how to work with the BioCyc Pathways mapping feature in Compound Discoverer 3.3 service pack 2 (SP2) application.

Save the date! There will be a Compound Discoverer Users Meeting on Saturday, June 3rd 2023 at ASMS in Houston, Texas. More details are coming soon.

Two new scripting nodes were added. 1. A script to export the Compounds table with multiple ions for each compound instead of the reference ion. 2. A script with custom calculations for PFAS analysis (for more details on this node please also see here).

We are excited to welcome you in person to Bremen, Germany again for the Proteome Discoverer & Compound Discoverer software Users Meeting from 12-13 December, 2022.

Please follow the link here for online registration.

Join us at the 18th International Conference of the Metabolomics Society Meeting. We’ll have a Compound Discoverer Workshop on Sunday, 19 June 2022 | 09:00 – 11:00 [CEST] at the Sercotel Sorolla Palace. You can sign up for the workshop here.

The high resolution accurate mass measurements that Orbitrap mass spectrometers provide are particularly valuable for metabolomic tracing experiments, termed “fluxomics” or “stable isotope labeling”. In these experiments scientists introduce stable isotope labeled compounds to create metabolic roadmaps to understand biological pathways and perturbations to systems. A major challenge is to interpret the results of these experiments, but Compound Discoverer software provides unique capabilities to determine isotopic enrichment in an untargeted fashion by leveraging the high resolution accurate mass data generated by Orbitrap instruments. Compound Discoverer software provides easy to interpret results through multiple powerful visualizations including isotopologue distribution charts and customizable overlays of labeling onto biochemical pathways through Metabolika. This powerful approach is an excellent complement to standard untargeted metabolomics and our differentiated products provides unique abilities and insights.

Compound Discoverer version 3.3 has just been released. New features in this version include:

• New peak detection algorithm
• Peak rating calculation and filter
• New method for retention time alignment
• Searches entire MSⁿ spectral trees against the mzCloud spectral library
• Improvements for Molecular Networking, and more.

You can download your trial version of CD3.3 from here.

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.
