A frequent goal, or subgoal, when processing data from
a quantitative
shotgun proteomics experiment is a list of proteins that are differentially
abundant under the examined experimental conditions. Unfortunately,
obtaining such a list is a challenging process, as the mass spectrometer
analyzes the proteolytic peptides of a protein rather than the proteins
themselves. We have previously designed a Bayesian hierarchical probabilistic
model, Triqler, for combining peptide identification and quantification
errors into probabilities of proteins being differentially abundant.
However, the model was developed for data from data-dependent acquisition.
Here, we show that Triqler is also compatible with data-independent
acquisition data after applying minor alterations for the missing
value distribution. Furthermore, we find that it has better performance
than a set of compared state-of-the-art protein summarization tools
when evaluated on data-independent acquisition data.
