# 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. You can then re-size the ROI for the tool after the Green Classify Tool to fit the needs of your inspection.

For example, if you want to further analyze an image based on the images classified with "5", you can enter a couple of different expressions into the Filter field.

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

With the expressions as filters, the tool only returns views tagged as "5" with a score above the Threshold parameter setting, by the definition of the filter syntax. Only views with a maximum score above the Threshold parameter are "found" by the Green Classify Tool.
