# ROI Options Following a Green Classify Tool

When a Green Classify Tool is the preceding tool, a filter can be applied to only display views that match a specific tag for the following tool. The ROI for the tool after the Green tool can then be resized to fit the needs of your inspection.

For example, if you were wishing to further analyze an image based on the images that were classified as being of the tag '5', you could enter a couple of different expressions into the Filter field.

- best_tag='5' and score > threshold
- tag![5]/score > threshold

With these expressions as filters, only views that were tagged as '5' with a score above the Threshold parameter setting would be returned, since by the definition of the filter syntax, only views with a maximum score above the Threshold parameter are "found" by the Green Classify tool.
