+===== Definition =====
+Context is a central notion in hEIDI. Basically, it contains identification results, i.e. a set of proteins identified by a set of peptides.\\
+There are two types of contexts in hEIDI:
+  * Search context: each identification result from Mascot, or from any other identification engine, is automatically "encapsulated" into one Search context.
+  * User context: it is created by the user in order to gather together several identification results into a User context. In order to have non-redundant sets of proteins for a given context, proteins need to be grouped to generate "Protein Groups".
+===== GUI: context tree view =====
-There are two types of contexts:

-  * User context
+A User context is represented by {{:usercontext.png|}}.\\
-  * Search context
+A context have either child contexts or identifications but can't have both at the same level.\\
+There are different reasons for grouping several identifications under a same context:\\
-===== Definition =====
+  * Same biological origin
+  * Same gel
+  * Same culture condition
+  * Same chromatographic column
