Sets of items and their annotations
This class describes sets, items and their annotations.
Internally, the method
mgsa indexes all elements of the sets before fitting the model.
mgsa must be run on several observations with the same gene sets, computations can be speeded up by performing this indexing once for all.
This can be achieved by building a
In order to ensure consistency of the indexing, no replace method for any slot is provided. Accessors are available.
