The first two Linear Discriminants (LD1 and LD2) from Linear Discriminant Analysis (LDA) of the combined normalised gene data sets. Reduced down to an optimal model with the transcript combination of MMP7, SLC5A8 and RECK which separated the normal (healthy) and the tumour colon tissue from Studies 1 and 2 and the cultured cell lines of ('empty circle' Study 1 normal, 'empty square' Study 2 normal, 'black circle' Study 1 tumour, 'black square' Study 2 tumour, 'black square with cross' cell lines).
