Simplified flow diagram of LipidMatch operations. The steps for identification of the feature at m/z 850.5604 and retention time (RT) 5.92 as formate adducts of PC(16:0_22:6) and PC(18:2_20:4) are shown as an example in grey boxes for each step. Note that the number of lipid identifications and fragments queried in the example are reduced significantly for illustration purposes. For Step 5, R1COO− and R2COO− were required for identification above an intensity threshold of 1000 in at least one scan across the peak
