-====== Protein grouping ======
-===== Algorithm =====
-==== Step 1 - Peptide grouping ====
-Peptides from different identifications - attached directly or indirectly to a context - are grouped.\\
-Peptides must have same sequence and same experimental mass to be grouped.\\
-Peptide grouping results in **new** peptides attached to the parent context and having child peptides
-{{proteinGrouping:GroupingStep1.png?248x148}}
-==== Step 2 - Protein grouping ====
-Peptides from a same protein or a same protein set are grouped.\\
-Protein grouping results in **new** groups of proteins and peptides, attached to the parent context.

-===== GUI - Execute protein grouping algorithm =====
-  - Right-click on the context node of your choice in the MSIExplorer view to display context sensitive menu and select "Algorithms->Group proteins..." {{ :proteingrouping:proteingroupingaction.png?300|Execute protein grouping}}
-  - Change parameters for protein grouping if needed. Validate.
-  - When grouping is finished, the color of the context name change to red in the MSIExplorer view.
