Since hEIDI 1.13.0, spectral count has been tuned. To achieve this, the new field leaves_match_count in MSIdb has been created in the peptide_instance table.

Spectral Count algorithm should have been run at least once :

1. Select one or more context of your choice (for which protein grouping have been executed)
2. Right-click and select Algorithms > Compute Spectral Count
3. Check/Uncheck optional parameters to compute. Then OK.

When Spectral Count algorithm execution is finished, you can retrieve results and parameters used in:

• properties of every Protein Groups in that context

• the context's protein groups list
