GeneNetwork displays only the strain averages ± SEM for each metabolite. To obtain the individual data for each animal, please use the link above under (Download datasets and supplementary data files). Note that this contains two entries for each animal: these are technical replicates. 

The very raw spectral data from the mass spectrometer can be downloaded on MassIVE ( http://massive.ucsd.edu/ProteoSAFe/static/massive.jsp?redirect=auth ) under the identifier MSV000079411. This spectral data is for all 290 individual animals, and it includes two technical replicates for each individual, for a total of 580 runs. The file size is 102 GB and we do not recommend downloading this unless you are specifically interested in re-analyzing the spectra from scratch and looking into the granular details of mass spectrometry metabolomics.
