Why is there no option for me to add explanatory rasters in the forest based classification tool?

I have a spatial analyst licence.

First, make sure you are opening the tool under the Spatial Statistics toolbox. There is a big-data processing tool by a similar name under the GeoAnalytics Desktop toolbox which does not allow Explanatory Training Rasters.

Then can you provide a screenshot of the tool? I can see the parameter in the circled location.

Thanks for the reply! I need to purchase the image analyst extension before I can see the raster option appear.
