In DIA-NN 2.3.0, we have added Deamidation (NQ) as an option in the GUI. There are good reasons for it :) You can try InfinDIA with any number of modifications selected, and check the RT differences between modified vs respective stripped peptides, for each mod - a way to validate peptidoform FDR.

The key molecules in immune responses are glycoproteins.

Why isn't glycosylation studied more intensively?

It should be.
It's a challenging research area, but a good one for ambitious & audacious scientists.

Time and time again, it's always the same picture. DIA-NN controls FDR correctly as data reliability has been the main goal at DIA-NN's conception back in 2017 and a priority since then.
