Consensus estimate. The points are normalized log2ratios in the 33-42-mb section on chromosome 3 of the TCGA-02-0104 sample from (a) the Memorial Sloan-Kettering Cancer Center (MSKCC) and (b) Harvard Medical School. The red lines indicate the mean values among the probes in segments obtained by the proposed circular binary segmentation procedure. Panel (c) shows a multi-platform consensus based on the combined data sets of Memorial Sloan-Kettering Cancer Center and Harvard Medical School. We found two more small segments, located in the 38.4-mb and 40.2-mb regions, which are indicated by the arrows. These were not identified in (a) and (b).
