- Worth noticing
- Its validation section covers four public datasets and explains why agreement figures from different reference lists are not directly comparable.
Field notes
The validation section identifies GlycoPOST and PRIDE datasets, sample types, instruments, and the reference lists used for comparison. It cautions that agreement against a broad search list is not equivalent to agreement against a smaller set of quantified glycans, and that unlisted calls are not necessarily wrong. The page also specifies settings for several labeling chemistries and positive or negative ion mode.
