Removing part of the model (Remove particles within model)

Hello Dear Developers and Users

As shown in the following figure; I have two models with the names of particlesSystem.vtk and ROI.vtk (Spherical shape).

I want to do two steps:

Step #1- Extract particles within ROI (It is OK)

Step #2- Remove these extracted particles from particlesSystem.vtk.

As shown in the following figure, I can do the first step using Extract Enclosed Points filter.

How can I do the second step? What filter should I use? I want to remove the particles extracted from particleSystem node.

Please guide me.
Best regards.

Check the “Generate Outliers” checkbox and use the outliers output.
