Hi! I found that an option ParticleAnalyzer.SHOW_ROI_MASKS causes unwelcome window appearing, altough
ParticleAnalyzer.SHOW_OVERLAY_MASKS does not.
val pa = new ParticleAnalyzer(ParticleAnalyzer.SHOW_ROI_MASKS + ParticleAnalyzer.EXCLUDE_EDGE_PARTICLES, 0, rt, 0.0, Double.PositiveInfinity)
such code I think has to be executed without any windows or at least with a method to suppress unwelcome behavior.
