Segmentation Mask/STL generation/Editing of all phases in a 4D Cardiac MRI dataset

Hi there,

I have used the Segment Registration Module to create a moving mask (whole heart and/or atrium + ventricle) of the 4D Cardiac MRI dataset. I was able to follow most of the discussion from here: Load multiple cardiac phases for segmentation/virtual reality - #2 by lassoan and the video (Create an animated 4D surface model by segmenting a single 3D frame - YouTube)

Ultimately I end up generating a segmented mask that and a transform output that mostly follows to what I want, with some areas that I would like to further tweak and edit.

I had several questions:

#1) What is the best/efficient way of going from here to create STLs for each timepoint (i.e. t1… t30), such that I can open up a moving STL on another software like Paraview?
#2) If there is something off in the transformed segmentation during one of the cardiac phases, what is the best way to edit this?
#3) How do I edit the transformed output?

Can provide more specific details if needed. Thank you!
