- Scatterplot matrix checks reproducibility of the data across different biological replicates of a sample.
- Metabolomics data are logged (base 2). High correlation values indicate highly reproducible signals across two replicates.
- Each circle represents a metabolite.
- Metabolites detected in only one of a pair of replicates are indicated as circles parallel to the x- and y-axis.
