(
a
) COVAIN-based principal components analysis (PCA) and sample pattern recognition for a MAPA protein
data matrix of two growth conditions of
Chlamydomonas reinhardtii
—mixotrophic and photoautotrophic [

].
Visible is the clear separation of the two growth types. The separation in the principal component analysis
is due to the differences in tryptic peptide
m

-ratio abundances. (
