+We will use the Query Tabular tool { %cite Johnson2019 % } to search the PepQuery-verified peptides against the concatenated dataset that contains peptides and proteins from SearchGUI/Peptide and MaxQuant. This step ensures all the PepQuery-verified peptides are assigned to their protein/protein groups.
