====== Context ======

===== 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 build "Protein Groups".

A User context is represented by {{:usercontext.png|}}.\\
A User context contains either child contexts or identifications but can't have both at the same level.\\

There are multiple reasons for grouping several identifcations under the same User context:
  * Same biological origin
  * Same gel
  * Same culture condition
  * Same chromatographic column
  * ...
