Flowchart depicting the steps involved in creating a multi-dimensional AMT tag reference peptide database of mass, normalized elution time (NET), and drift time information (Methods 2.3 and 2.4). Samples were analyzed using LC-MS (LTQ Velos Orbitrap) to establish NET and elution time information and also using LC-IMS-TOF MS so that drift time values can be associated with the peptides.
