The MS and NMR datasets is composed of: a ReadMe file one Excel file named "Sample Rosetta Stone" containing the MS and NMR dataset sample description, the MS dataset: - a "Grains" directory containing LCMS raw files in mzML format. They are organized according to the following groups: Blank, MON810_I_woR, MON810_T_woR, Nk603_I_woR, Nk603_T_woR, Nk603_T_wR and QC, - a "Pellets" directory containing LCMS raw files in mzML format. They are organized according to the following groups: Blank, QC and T0-1 to T0-9, the NMR dataset: - 21 NMR spectra directories (containing 1H single-pulse (zg) NMR spectrum for each maize grain extract sample and 1 directory GMO-11-2D containing 2D (COSY and HSQC) spectra for “NK603 transgenic without roundup” extract sample) in Bruker format, - 18 NMR spectra directories (containing 1H single-pulse (zg) NMR spectrum and 1H CPMG spectrum for each pellet extract sample) in Bruker format.
