Description n/a
Data processing Spots were quantified in ImaGene 5.6.1 software using default settings. BAC clones were positioned along the genome according to the July 2003 freeze. After exclusion of flagged spots, the average of the triplicate spots was calculated for each BAC clone and 2log ratios (tumour/normal reference signal) were normalised by subtraction of the mode value of BAC clones on chromosome 1-22. BAC clones with flagged spots were excluded from analysis.

Data table header descriptions
ID_REF
Signal Median CH1 spot signal channel 1 (Cy3)
Background Median CH1 background signal of channel 1 (Cy3)
Signal Median CH2 spot signal channel 2 (Cy5)
Background Median CH2 background signal of channel 1 (Cy5)
Log2ratio
Flag A flag to highlight spots that suffer from poor printing and other experimental artefacts (0 acceptable; 1-4 not acceptable)
VALUE same as UNF_VALUE but with flagged values removed
UNF_VALUE Normalized value of the log2ratio. Flagged features are excluded. Values where also deleted if the each triplicate had a Standard Deviation higher than 0.2.
