From: Normalization method for metabolomics data using optimal selection of multiple internal standards
The NOMIS method as a tool to select the best set of internal standards used for normalization. The coefficients of variation for different combinations of internal standards used in the NOMIS method as applied to the liver dataset (1470 peaks). Only sub-region of m/z and retention times are shown, corresponding mainly to phospholipids, sphingolipids, and diacylglycerols. The internal standard combinations are listed in the plot titles.
