The data presented here as an example was generated by the West Coast Metabolomics Center at UC Davis. It contains 5 different data sets from 5 different mass spec runs. 
The initial samples were prepared such that they were separated into an aqueous and organic phase. The aqueous phase was split into 3 different mass spec runs, 
biogenic amines in positive mode, biogenic amines in negative mode, and primary metabolism. The organic phase was split into the remaining 2 mass spec runs for 
lipidiomics in positive mode and lipidomics in negative mode. When depositing into the Metabolomics Workbench, each different mass spec run must be a separate 
analysis, so there will be 5 mwTab formatted files generated for this example. Due to how the data is given by West Coast each of the analyses will not be in their own 
folder. The data for different runs is combined together in 1 file for biogenic amines and lipidomics, the positive and negative mode data are both in 1 file. The sample 
data is also in its own separate file, so it is easier to keep all of the data together in one folder when running the messes package commands.
