Figure 3

Scan/rescan correlations for tumor 248. Plot shows background subtracted signals from the original laboratory scan (x-axis) plotted against the signals from the rescan performed in the other laboratory. All of the individual features from all of the16 arrays are plotted. All 16 arrays for tumor 248 were scanned in the hybridization lab, then shipped to the other lab and rescanned (32 scans total from 16 arrays, on 2 slides). Green data points are from the Cy3 channel, red data points are from the Cy5 channel.
