====== How to run and access spectral count data ======

:!: 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. For this reason, an MSIdb migration has to be realized to add & populate this field if you intend to use the hEIDI 1.13.0 version.

===== Run the Spectral Count algorithm =====

Spectral Count algorithm should have been run at least once :
  - Select one or more context of your choice (for which protein grouping have been executed)
  - Right-click and select ''Algorithms > Compute Spectral Count''
  - Check/Uncheck optional parameters to compute. Then ''OK''.

===== View spectral count data =====
When Spectral Count algorithm execution is finished, you can retrieve results and parameters used in:
  * [[accessproperties|properties]] of every Protein Groups in that context
{{:spectralcountresultpropertysheet.png| Protein Group properties}}

  * the [[browseContextProtGroups|context's protein groups]] list
