thanks

Thanks,

I dont have paraview to be able to visualize isosurface and corresponding points but I am working on getting access to be able install it on the computer i am working on. 

I was wondering why it works for 256 correspondence points. Isnt the points provided for initialization the same for 256 as 2048? Also if this is the case how do I change the initialization poiints.

Thanks again

Hi Kenneth,

This usually happens if the points you are providing for initialization
doesn't lie on the isosurface of the respective distance transforms, as
a visual QC, you might want to load a sample nrrd file in paraview then
load its corresponding points and make sure that the points lie on the
isosurface ...

hope this would help

regards
Shireen
