ExtraEffects not working on transformed segments

[ottensmeyer]

I'm trying the ExtraEffects tools to segment femoral veins in CTAs (arteries great, veins have lower contrast, trying to avoid much manual clean up), couldn't get the control-click to work on Local Threshold, no response on Fast Marching, etc. I found the comment from April '21 by danpak94 at: https://discourse.slicer.org/t/new-segment-editor-effect-local-threshold/9233/42 and can confirm that while the tools work fine on non-transformed segments, I also have the problem that the tools don't like to work with segmentations that have been transformed (both rotated and translated in my case). A workable workaround for me is to make a separate, non-transformed segmentation, but that may not be appropriate for everyone.

Thanks for reporting. Which effects do you find are not compatible with transformed segmentation? Do you use a rigid transform (linear transform with translation or rotation) or a warping transform (grid, bspline, thin-plate-spline)? What is the reason for having the segmentation under a transform (varying slice spacing, curved planar reformatting, ...)?
