-====== Context definition ====== 
- 
-Contexts are a central notion in hEIDI. Basically a context contains an identification result : groups of proteins identified by groups of peptides. This definition can be equally used for identification results issued from a search engine such as Mascot for example as well as identification results build up from many other identifications results compiled together. hEIDI distinguish two types of context :  
-  * a Search context wich is a context associated with the identification result issued from a single search in Mascot (or other search engine). Each time a new search engine result is saved in the database by IRMa, a new search context is created. 
-  * a User context is created by the user in order to organize and aggregate multiple search and/or user contexts. ​ 
- 
-After having opened an MSI session in your project, you can retreive the User context and Search context hierarchy in the MSIExplorer view.

-===== User context ===== 
-In hEIDI, a User context is represented with {{:​usercontext.png}}.\\ 
-A User context can contain either contexts or identifications,​ but you can't have both under the same context.\\ 
-Below is an example showing a way to organize identifications.\\
