- | ====== 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 ==== | ||
- | |||
- | {{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 | | ||
