T17_75_37_output_fused
T17
Data processing Bluefuse software version 3.4 (BlueGnome, Cambridge, UK) was used for automatic feature extraction. Spots were excluded when the quality flag was below 1 or the confidence value was below 0.1. Log2 tumor to normal ratio was calculated for each clone and median block normalization was used to normalize the data.
