-Context is a central notion in hEIDI. Basically, it contains identification results grouped in a set of proteins identified by a set of peptides. There are two types of contexts in hEIDI:
+Context is a central notion in hEIDI. Basically, it contains identification results, i.e. a set of proteins identified by a set of peptides.\\
-  * Search context: a Mascot identification result - or an identification result from any other identification engine - is encapsulated in a Search context
+There are two types of contexts in hEIDI:
-  * User context:
+  * 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, protein grouping process need to be run.

+A context have either child contexts or identifications but can't have both.\\
+There are different reasons for grouping several identifications under a same context:\\
+  * Same biological origine
+  * Same gel
+  * Same culture condition
