Data Analysis Details Information

ID DS1
Title Peak detection, alignment and characterization using PowerGetBatch
Description The PowerGetBach software (version 0.5.4, http://www.kazusa.or.jp/komics/software/PowerGetBatch) was used for peak detection. In the case of the sample with more than three biological or technical replications, a single parameter setting for high resolution (Method 1-4) was applied for peak detection. In the case of the sample without replications, a single raw datum was processed using three different parameter settings for high resolution (Method 1-4). The data obtained in low-resolution settings (Method 5 and 7) was processed with a single parameter setting. The detailed peak detection parameters for PowerGetBatch are available at the Plant Metabolome Repository website (http://metabolites.in/plants/data/PGB_params.zip).
  The detected peaks in the samples with high- and low-resolution analyses and in the mock samples were aligned using PowerGetBatch software for each positive and negative mode. The reproducibly detected peaks in the samples and absent in the mock samples were selected as valid peaks. The selection was performed manually using Microsoft Excel with consideration of the analytical replications of the sample. The most intense and major patterns of the MS2 and MS3 spectra were selected among the alignment results for each peak. Searching candidate compounds in compound databases and prediction of flavonoid aglycones using FlavonoidSearch system for valid peaks were performed as described in the annotation details AM1.
