See comparison principles if needed.

You can compare :

• an existing parent union context with its children,
• or several contexts with a *virtual* parent union

Activation conditions:

• Selected contexts must be grouped AND saved to MSIdb.
• Selected contexts must not contain identification that intersect (if you are interesting by such a possibility, ask your Admin)

1. Select the parent context of your choice
2. Right-click and select Algorithms > Compare with > All children/Union parent
3. The comparison window displays the result
4. Select in the droplist the properties (peptide similarity, protein similarity, accession, etc.) you want to compare

1. Select the contexts of your choice: at least 2 contexts, may be Search or User contexts (or mixed), not having necesserally a parent/children relation
2. Right-click and select Algorithms > Compare with > All children/Union parent
3. The comparison window displays the result
4. Select in the droplist the properties (peptide similarity, protein similarity, accession, etc.) you want to compare
