Why are some experiments lacking data for the various median results?
Data entered before January 2001 does not contain these median result data. Before this time, our default file format was based on Scanalyze, which does not have these columns. Since the beginning of 2001, we changed our database so that it was able to store all columns produced by Genepix, which is used by most people entering data into UNC MD, while continuing to support Scanalyze.

Background is determined on a local, spot-by-spot basis. If you are using Genepix, the background pixels include all of the pixels within a circular region that surround the feature of interest unless they meet one of the conditions listed below. The circular region has a diameter of three times the diameter of the current feature indicator. The pixel is excluded from background calculation if one of the following is true: 1) the pixel resides in a neighboring feature-indicator 2) the pixel is not wholly outside a two pixel wide ring around a featu
