This will open the Feature Selection window.

- It is recommended to select all features for the lineage markers. (We also select all features for any imported computed features).

Your classifier is created and will appear in the classification panel.
When you create a classifier, a population set will be created for its labels called ‘Labels_{CLASSIFIER_NAME}’.

You will add labels to this population set in the [next section]/(/documentation/classification/add-labels).
