Experiment annotations
DB stores
hybridization intensities as well as
experiment annotations
.
They are
entered in a convenient way
.
They are
stored as defined values
rather than free text ...
and can therefore be used to
characterize experiment clusters
such as ...
this

counting frequencies
for all values of all annotations ...
characteristic (over- or underrepresented) values are
listed
.
