(Lower panel) Circular heat map representation of unsupervised hierarchical clustering of the data coming from analysis of 47 kernel samples (rows) grouped by compound type (columns); (Upper panel) Circular heat map representation of unsupervised hierarchical clustering of the data coming from analysis of 47 wholemeal flour samples (rows) grouped by compound type (columns).
Shades of red and blue represent increase and decrease of a compound relative to the median compound levels (see color scale).
