    3  * Class `QuantileNormalization` in `src/net/sf/basedb/plugins/QuantileNormalization.java` extends `AbstractNormalizationPlugin`, and the latter contains several methods to access data, all using method `VirtualColumn.channelIntensity(int channel)` to retrieve the data from the database. For transformed data in log-2 or log-10 format, this means that the data is fetch in untransformed format, and will be stored as such after normalization.
