Raw MS imaging data for most of our previous publications are now available at METASPACE (https://metaspace2020.eu/), MS imaging data repository and web-based metabolite annotation tool for high-mass resolution data at EMBL.

Please note that not all data are available as it requires <3ppm mass accuracy while our previous instrument has mass accuracy <5ppm. We tried our best to re-calibrate with a few known peaks in the dataset, which did not always result in success.
Most data are from maize root, leaf, stem, and seeds.
Our recent work on Kendrick mass defect analysis of aged fingerprints by Andrew Paulson (ACS Central Science, 2022, 8 (9), 1328-1335) is highlighted in several news outlet!
