This is part of a global idea which is to improve global performance in hEIDI.\\ | **Since hEIDI 1.11.0**, a new peptide/protein grouping algorithm has been implemented.

VELOS), and loading all data in memory in one hEIDI session is no more possible (as we did before hEIDI 1.11.0). \\ | + | Indeed, datasets become bigger and bigger (ex.

| We have started to optimize the peptide/Protein grouping algorithm as it requires to load a complex object tree and so is very memory consuming. Other algorithms will be optimized progressively in further hEIDI versions.\\ | We have started to optimize the peptide/Protein grouping algorithm as it requires to load a complex object tree and so is very memory consuming.

| - | Paradoxically, the grouping is little bit slower compared to previous hEIDI versions. But, initial loading and save operation will be quicker. | + | **What are the changes for the user:** |
| - | + | * Paradoxically, the grouping is little bit slower compared to previous hEIDI versions. But, initial loading and save operation will be faster | |
| - | the MSIdb must be saved before launching grouping. The peptide/protein grouping is automatically saved to MSIdb as well. | + | * The MSIdb must be saved before launching grouping |
