Panels are defined as a set of Assay definitions.  This is similar to tao a Project defined as a set of Experiments.  The major difference is that the Project Experiments are ordered via Project Steps whereas Assays are a simple un-ordered set within a Panel.<br /></p><p><br /></p><p>Each Assay gives rise to one or more Experiments.  If the Assay is of type "Panel" it gives rise to a Panel Experiment.  A Panel Experiment is a collection of experiments derived from the collection of Assays within the Panel.  Note that an Experiment can only belong to <b>one</b> Panel Experiment whereas the Assay can belong to several Panels.<br /></p><p><br /></p><p>When Results are loaded they are loaded to each individual Experiment - Panel Experiments do not have Results loaded directly.<br /></p><p><br /></p><p>As each Experiment can belong to one or more Projects so each Panel Experiment can belong to one or more Projects. The association between the Project and the Experiment is sub-classed to define a Project Single-Experiment and a Project Panel-Experiment.  <br /></p><p><br /></p><p>When displaying the graph of Experiments in a Project the Panel Experiment should be displayed in preference to a set of single Experiments as the resulting network is considerably more comprehensible.  Drill down to the set of Experiments contained in the Panel Experiment should be provided.<br /></p>
