> You have three options, you can use all, but the first one is the most important: crop your input volume to the region of interest & resample to have sufficiently high resolution using the Crop volume module: specify your ROI, select Isotropic spacing, select sufficiently low spacing scale value (the lower the value, the more details you can preserve during segmentation, but more memory and processing time you will need; typically 0.5 … 0.2 should work), select bspline interpolator smooth the …
