Context is a central notion in hEIDI. Basically, it contains identification results. A context contains 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 “encapsulated” into a Search context.
• User context: it is created by the user to gather together several identification results. In order to have non-redundant sets of proteins for a given context, protein grouping process need to be run.
