  1. Protein false discovery rate confidence (Protein FDR Conf) = High means FDR < 0.01; number (#) of peptides = the number of distinct peptide sequences in the protein group; Number of peptide spectrum matches (#PSMs) = the total number of identified peptide sequences for the protein; # Unique peptide = number of the peptide sequences unique to a protein group; Number of amino acids (#AA) = the sequence length of a protein; Molecular weight (MW[kDa]) = calculated molecular weight of the protein; Found in sample = high, peak found, or peak not found.
