The validation form handles several settings, especially :

  * PSM Filters : use the selection box and the green button to add more filters on Peptide Spectrum Matches to be applied during the validation process : Score, Rank, Sequence Length, E-Value and P-Value.

  * PSM Validation Parameters : choose on which param the Peptide FDR should be applied : Score, E-Value or P-Value.

  * Merging Mode : determines if the merging operation should be done before the validation (on result sets) or after the validation process (on identification summaries)

When ready, click on //Validate// to launch the validation task. You can see it in the tasks panel. 
When the validation finishes, a notification will be displayed and the node icon will be colored in green.

See [[prolineconcepts:rsvalidation| more details about the validation process]].
