Context comparisons
Definition
The purpose is to search for similar 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
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 |
 |  |  |
