mzCloud will be undergoing some changes. As part of our migration away from Microsoft® Silverlight™, we will be releasing a new mzCloud spectral library. This new version will have an entirely new user interface and be supported by all major web browsers. Our goal is to have the new mzCloud library up and running prior to the end of life of Silverlight (12 Oct 2021). However, in order to avoid any potential interruption, and to provide clarity on what you can expect from mzCloud.org in the coming months, we provide the following information.

  • If you are a Compound Discoverer user, there will be no interruption to your data processing in Compound Discoverer during the migration process. Current Compound Discoverer versions will continue to be able to access the current mzCloud library throughout the process and continue to be supported after the migration. We will keep you informed of improvements and implementation in future Compound Discoverer versions at myCompoundDiscoverer.com

  • If you are a TraceFinder user, we will continue to provide offline libraries for you to use with TraceFinder and mzVault with no interruption through the migration process.

  • If you access mzCloud through the web user interface, there are some steps to take to prepare for the migration process so there will be no interruptions.
    • If you have previously used mzCloud on your computer, you will be able to use Microsoft Edge in IE compatibility mode to access mzCloud after Oct. 12, 2021
    • If you want to be able to access mzCloud on a compouter that you have not previously used to access mzCloud, download and install Microsoft Silverlight prior to Oct. 12, 2021. You will then be able to access mzCloud using Microsoft Edge in IE compatibility mode.
After the migration to new mzCloud is complete, the “Enter Library” icon from mzCloud.org will direct you to the new mzCloud library automatically. We look forward to bringing you an even better experience with new mzCloud as we continue to add more spectral data on more compounds while also improving the capabilities of the library to help you more easily identify compounds.
