-====== Context comparisons ====== 
- 
-===== Definition ===== 
-The purpose is to search for similar [[proteingroups#​protein groups]], i.e. protein groups: 
-  * having the same set of proteins 
-  * identified by a same set of peptides 
- 
-The Dice coefficient is used to measure similarity (result ranges from 0 to 1).

-==== Compare two contexts with each other ==== 
- 
-{{context:​contextComparison.png?​260 }} 
-The "Each other" context comparison algorithm will compare every protein groups of the first context with every protein groups of the second context.\\ 
-Comparing two protein groups each other means  
-  - Checking the similarity of their protein sets (sameset and subset) 
-  - Checking the similarity of their peptide sets 
-  - Checking if "​master"​ proteins are identical 
- 
-==== Compare N contexts ==== 
- 
-^  Similar with previous comparison ​ ^  Compare each context with a unique reference ​ ^^ 
-|                                                 ​| ​ Build the reference ​ || 
-|  easure similarity and "best alignment"​. ​ |  Identification union  |  ...aka the parent context ​ |
