# NullVisualClusteringItemSourceData

Removes (deletes) the samples from a visual clustering item, but does not remove the generated training. This means that the item can still be clustered but the source data (samples) are no longer stored in the database.

Removing the source data means that the training cannot be updated in future. If future versions of Media Server feature enhancements to visual clustering that require retraining, you will need to supply the source media again.

Type: synchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database that contains the item. | Yes
`identifier` | The identifier of the item for which you want to remove the source data. | Yes
