MetaboLyzer’s transformation and normalization workflow. Complete-presence data (ions that possess a non-zero value in a user defined percentage of both control and treatment datasets) are first transformed by either the standard log transformation or the inverse hyperbolic sine transformation. Normalization is an option only if the standard log transformation is chosen. After transformation and/or normalization, standard statistical testing will be conducted. The transformation and normalization stages can also be completely bypassed so that the original data can be analyzed.
