The seven archetypes from archetypal analysis are transformed into the PCA space through a basis transformation. Each Study is indicated with a specific color. Study 1: GREEN, study 2: CYAN (samples #48-74) and BLUE (samples #75-128), study 3: RED, study 4: MAGENTA, study 5: ORANGE. The phenotypes are indicated with symbols as “Early”, “Late”, “Mucoid” and “Hypermutator”. The reference strains PAO1 and PA14 from study 1 and 2 are indicated with a symbol as “Reference”.
