This step is available only if at least one reference well is defined in the plate mapping step. ![Reference Analysis summary](https://cdn.document360.io/dde9293e-c107-4b3e-9774-9c9c296ed970/Images/Setting/assay-exec-reference-analysis-home.png?sv=2026-02-06&spr=https&st=2026-11-11T00%3A35%3A39Z&se=2026-11-11T01%3A35%3A39Z&sr=c&sp=r&sig=0asXmpsmv9xcKRbbaj7wf0eMPAfdp%2Byf3YeRaM8NsRA%3D) ## From the Run Template Before accessing the `Reference Analysis` page, some information is pre-calculated using the run template configuration: - How the data is aggregated: - Aggregations define how individual data points are grouped for analysis (e.g., grouping all data points for a given sample across tested doses to calculate an IC50). - The automatic analysis: - Some data may be automatically invalidated if the designer defined such rules. - The annotation types: - Annotation types may be added to wells or plates, allowing you to add extra values. ## Reference Analysis ### Validate or Invalidate a Data Point When analyzing data, you can manually invalidate data points. Select the data and click the `Invalidate` button in the top bar. The analysis will be recalculated without the invalidated data (e.g., IC50). For more information, see the [How To: Validate or Invalidate Data guide](/public/docs/validate-or-invalidate-data). ### Add Annotation Values and Comments You can add, edit, or delete annotation values, or add comments to a group using the left panel. See [How To: Add Annotation Values or Comments](/public/docs/add-annotation-values) for instructions. ### Update Analysis Parameters for an Aggregated Group If needed, you can manually update the parameters used to calculate a data point for an aggregated group. See [How To: Update Analysis Parameters](/public/docs/update-analysis-parameters-for-a-group) for instructions. ## Reference Analysis Settings Aggregations are created by the designer in the `Reference Analysis Settings` page. This page is automatically skipped in `Execution Mode`, but you can access it using the breadcrumb bar. ![Reference Analysis settings summary](https://cdn.document360.io/dde9293e-c107-4b3e-9774-9c9c296ed970/Images/Setting/assay-exec-reference-analysis-settings.png?sv=2026-02-06&spr=https&st=2026-11-11T00%3A35%3A39Z&se=2026-11-11T01%3A35%3A39Z&sr=c&sp=r&sig=0asXmpsmv9xcKRbbaj7wf0eMPAfdp%2Byf3YeRaM8NsRA%3D) ## Next Step You can freely navigate between `Well Validation` and `Reference Analysis` pages using the `Back to Well Validation` button. From the `Well Validation` page, continue the analysis by proceeding to the next step: [Sample Mapping step](/public/docs/sample-mapping-execution-mode).
