Would love to have an orbitrap schematic real time thingy to see the ions being counted.. wouldn't you too?

QcxMS simulation to retrieve unknown? here is an unknown trioxilin. I used 4 different deprotomers of this trioxilin each at two different energy. Average it all, and run a search (based on a simplecosine and a few simple tricks, like removing too many even mz/weighted-fit) against oxidized PUFA

pubs.acs.org/doi/10.1021/... Another step for oxylipins. Now with ion identity. Thank you the Barbas team for this great collaboration . And of course @angelsi.bsky.social

Hey Avogadro fan.. 1.2 version only. Is there like a magic way to properly draw and optimize (just for the sake of then going to xtb) some cobalt carbonyl complexes . Mine goes bunker's everytime . First time with metal for me.

Today they told me no more than an hour for weekly presentation in the group.. I did 20 min too long and still got my cake.

The full revident is reading for our initial training

We are looking for a CNRS chargé de recherche position in our team in Montpellier with great expertise on computational methods for the analysis of mass spectrometry data. And a love interest in Lipid if any. Don't hesitate to contact. #massSpec

@mingxunwang.bsky.social hey hope all is good. Is it a bug in gnps2 screen .. can't be 0.7 by default can it?

The deprotomeric dance of oxylipins in a mass spectrometer compute by QCxMS

@simonhammann.bsky.social too bad it is an MDPI right? #lipidmediators

plenty of good stories if you love lipid and oxidation; #lipidthug www.amazon.com/Breaking-Cha...

You've got to buy this great book and so funny to from the great Mikhail Shchpinov

The beauty of proper in silico ms2 fragmentation, QCxMS @grimmelab.bsky.social. your typical complex H dance for fragment m/z 203 of deoxyPG... Or The second from QCxMS also acknowledge deuteration studies..

You don't want to miss that .

hello GNPS2 lovers.. is there a way to go from GNPS2 to dashboard without deposit the data in massive or whatnot or by dropping them again in dashboard. example, with this GNPS gnps2.org/status?task=... how do you get the mzml files in dashboard? using a particular ID numbers?? cheers

Forgot the @terezapupuco.bsky.social @camilleog.bsky.social 😜

Here is our last paper, a novel deoxy like prostaglandin from DHA from Pavlíčková chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/... total synthesis, high resolution msms and its simulation by QCxMS and finally a little bit of molecular networking. Enjoy. We are at our best here. Chemist 2.0😅

Out today in @nature.com: Together with the Honigmann, Shevchenko, Drobot and Hof labs, we present a general workflow for imaging the localization and transport of individual lipids in cells and mapping their metabolism. www.nature.com/articles/s41...

Nice work, demonstrating determination of omega positions in lipid acyls using only RT prediction! www.nature.com/articles/s41...

Je suis photographe animalière, je vends mes photos pour vivre. Un partage, c’est plus qu’un simple clic : c’est me rendre visible. Merci ! 🙏

Never give up on the ANR granting..😅 ❤️ with one month delay because as good french we complained. thanks for supporting us with the new project Ima-ClickChe. The future of neuroprostane signaling is there. #ANR #oxylipin @agencerecherche.bsky.social

Looks like the file summary of gnps2 is down.. @mingxunwang.bsky.social cheers

Can you spot the fifth renegat?

So just imagine the number of potential bioactive precursor hepoxilins. Stagerring

Cinq more or less were known to man...now A little bit more

I am trying to make a gesture on how many novel trioxilins we discovered in one single analysis. Serendi_lipid. My new fav. #issfalquebec

like really no one

Whose voting for that slide at #issfal Québec?

Anyone from MAssQL? CANNOT get through the filtering option in gnps2? @mingxunwang.bsky.social If you have time, the mzml is fine for gnps2 but somehow does not pass the filtering before if added before. gnps2.org/status?task=... Thank you for any help from the community too.

After years of development and preparatory works which you might have seen on this profile, a major milestone is achieved: g-xTB marks not just an evolution, but a revolution in the capabilities of semiempirical quantum chemistry. Convince yourself! A thread. 🔗 chemrxiv.org/engage/chemr... #compchem

@drchrispook.bsky.social @billsimmons.bsky.social can you beat that?

MASSQL lover. Do you have a way for extracting the colored-highlighted-filtered features into cystoscape? How can you retrieved them back there to get good quality images? Cheers

@mzmine.bsky.social hey guys, how feasible would it be to visualize the (XIC or base peak) chromatogram of the precursor(s) from which we selected one particular fragment and only those precursors. same as the picture but with the XIC of the precursor not the selected fragment..;
