A week with Judita Koreiviene, Jurate Karosiene and their Algology (Phycology) lab at the Natural Research Center in #Vilnius. We had fun setting up the HPLC method for #microcystins and organizing an HPLC seminar. A new collaboration has started and exciting results are coming soon....

Implementing the MCheM setup is pretty easy, and all reagents and hardware components are commercially available and relatively cheap.
MCheM data analysis is supported in @mzmine.bsky.social @gnps2.bsky.social and SIRIUS (@brightgiant.bsky.social) and free for academic researchers.

Distilled rule of thumb for optimal Cosine cutoffs at various n matching MS2 fragments in #metabolomics ID:

Cosine > 0.90 - 0.05*MMP

Aligns well with ~80% at 3 matched fragments I learned before.
