Additionally, the small decoy database (11 753 peptides) for mProphet model can increase the likelihood of incorrectly assigning a "true" hit as "false." Therefore, relaxing the FDR cutoff would minimize these potential false negative peptide IDs and increase the power of the experiment. As a result, peak area inform
