I used a core facility to run a metabolomics experiment, and essentially all I got back was just a huge spreadsheet with relative intensities for each metabolite.  Is there a crude and quick methods I can use in order to determine fold changes and map the metabolites to their respective pathways? Many of the metabolites were given KEGG ID numbers (a large number do not though), so is there a way to use KEGG to do pathway mapping and to generate say a heatmap in order to make the data much easier to understand?
