This type of stuff always freaks me out! But it seems unlikely that the coumarin content would actually be on toxic levels

I think they used both? Honestly I'm cool with MS1 ID (better than throwing out perfectly good features) especially if there's a validation experiment, but it should be with a reasonable tolerance and formula/rt matching. I tried to check the raw data but the DB didn't find the ID :/

Top-4 DDA for a C18 separation leading to 631 differential metabolites? I do 2 complementary HILIC runs, top-15 DDA, and 600 _metabolites_ (not differential) is a 99th percentile result. I guess some of these annotations come from MS1 matching at that super generous 30 ppm allowable error?

I hope that's the case because alternatives are worse 😆 And agreed I expect more rigor from Cell Metabolism
