- | ====== 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 }} | ||
- | 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. | ||

- | ===== GUI: Compare contexts each other ===== | ||
- | {{:context:compareeachother.png |Compare contexts each other}} | ||
- | - Select the two contexts (for which protein grouping has been executed) you want to compare each other | ||
- | - Right-click and select "Algorithms->Compare with->Each Other" | ||
- | - The comparison window display the result | ||
