Layout of samples on the Illumina BeadChips and flowchart of the analysis approach. A, Illustration of the positions of samples on the 18 BeadChips, processed in five batches (also referred to as 'runs') corresponding to the five different days on which the samples were hybridised and scanned. UHRR samples are labelled as C1-18. Duplicate breast tumour clinical samples are labelled a and b. The pre- and post-treatment biopsy samples are identified by a triangle to the left and right of the sample IDs, respectively. B, Flowchart of analysis methods
