Table 5. The distribution of samples with incorrect 1-st order predicted pathway class in 11 pathway classes.

Metabolic pathway class	Number of misclassified samples
Carbohydrate Metabolism	105
Energy Metabolism	32
Lipid Metabolism	79
Nucleotide Metabolism	26
Amino Acid Metabolism	146
Metabolism of Other Amino Acids	79
Glycan Biosynthesis and Metabolism	21
Metabolism of Cofactors and Vitamins	107
Metabolism of Terpenoids and Polyketides	107
Biosynthesis of Other Secondary Metabolites	95
Xenobiotics Biodegradation and Metabolism	113
Total	910 a

^aThe value in this cell is larger than the total number of samples with incorrect 1-st order prediction because some samples belong to more than one pathway class.
