-====== 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).
-{{context:diceCoef.png?102x50}}
-==== Compare two contexts with each other ====
-{{context:contextComparison.png?260 }}
-It compares 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 (FIXME sameset and subset)
-  * Checking the similarity of their peptide sets
-  * Checking if "master" proteins are identical
-==== Compare N contexts ====
-This comparison is similar to the previous one: similarity measure and FIXME "best alignment"\\
-Each context is compared with a "unique reference". First of all, this reference is built from the identification union, i.e. the parent context.
