Exited to share our latest work! Out now in @natcomms.nature.com Koina aims to transform how #proteomics uses machine learning. You no longer need to be a tech wizard to use ML and now can easily run #ML models. Integrated with FragPipe, Skyline and EncyclopeDIA! www.nature.com/articles/s41...

This project started 5 years ago. It led us to add isotope-labeling support to #FragPipe/#IonQuant. Since then, the tools have grown so much and are now widely used in #Chemoproteomics. Huge thanks to everyone, and special thanks to @stephanhacker2.bsky.social and @pzanon.bsky.social

How can we study target engagement and selectivity of covalent inhibitors? Which electrophilic probes are best suited to study a certain amino acid? Our study on "Profiling the proteome-wide selectivity of diverse electrophiles" is published in Nature Chemistry.(1/7) www.nature.com/articles/s41...

It was a great pleasure to teach #FragPipe at the Biological Proteomics for Beginners workshop at #UCSD, sponsored by Thermo Fisher Scientific. We had a fantastic group of grad students, postdocs, and professors. Yes, I even got to teach UCSD professors how to analyze bottom-up proteomics data 😁

#MSFragger Open Search has been around for a while now and used by mass spec folks to screen for chemical artifacts and adducts, e.g. in chemoproteomics data. Happy to see it got 'discovered' by a broader community who are now reporting all sort of cool biological PTMs www.nature.com/articles/s41...

Conventional proteomics searches struggle with many modifications and fully open searches may be difficult to interpret. We introduce a "detailed" mass offset search in #MSFragger boosting interpretability and localization especially in complex cases (e.g. FPOP data): www.biorxiv.org/content/10.1...

Don't tell PD, but I have quietly switched all of my analyses to Fragpipe. What an extremely powerful software. I'm often amazed at the sheer quantity of information I can get using Fragpipe. Thanks to everyone who recommended it.

Excited to be one of the guest editors! We’re calling for papers on cutting-edge #proteomics and #metabolomics in #multiomics research. Looking forward to your submissions!

In addition to these exciting events, I’ll also be one of the panel members at the single-cell proteomics Evening Workshop on Wednesday. Looking forward to the discussions ahead!

Wow, a record breaking number of the Nesvizhskii lab members attending #ASMS2025! 9 posters, 3 evening workshops, and one Bioinformatics Hub on #FragPipe. Plus multiple collaborative posters with other groups. See you in Baltimore! PS. Below is our recent group photo, including all those attending

The power of #MSFragger open search! “we applied the mass-tolerant search engine MSfragger and found that phosphorylation as well as ubiquitination were well preserved after XDNAX. To our great interest, we found an additional modification of 321 Da occurring only in the irradiated SILAC channel”

If there any #Sciex decision makers here on Bluesky - I urge you to reconsider. Skyline/Proteowizard support is not only important for your customers using these tools, but it also benefits other bioinformatics efforts that depend on these tools.

In this release, one of the major improvements is LFQ using IonQuant. Thanks to this excellent preprint (www.biorxiv.org/content/10.1...), we identified and fixed a suboptimal step in the XIC. We're always eager to listen to feedback from the community!

DDA is still great for many applications, and #MSFragger-DDA+ improves peptide identification sensitivity via full isolation window search. Huge boosts in IDs, including Astral DDA! Fully integrated in #FragPipe, simply annotate your DDA files as DDA+ and RUN. www.nature.com/articles/s41...

Sitting at Pike Place Market in Seattle at 7am in the morning, sipping coffee with my son, a long layover on the way home from Taipei. Otherwise I would do a long post. DiaTracer in #FragPipe work really well, making library-free analysis of any diaPASEF data possible. www.nature.com/articles/s41...

Looks interesting, and they already coupled it with MSFragger/FragPipe to search MS data using their fasta. I recommend using the group FDR option (available in FragPipe; requires annotating the headers in fasta in certain way) or a two-pass search option (canonical DB->unassigned mzML->custom DB).
