+ | 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". | ||

- | * Search context | + | A User context contains either child contexts or identifications but can't have both at the same level.\\ |
- | ===== Definition ===== | + | There are multiple reasons for grouping several identifcations under the same User context: |
+ | * Same biological origin | ||
