This should work, you might want to increase the number of optimization iterations, say 500 or 800 ... it should be fast ...

So I should use the .lpts files in the correspondence.xml file? Right now I haven't specified anything. attached is my correcpondence.xml file

I assume that these points are output of shapeworks from previous run, right? if so, use the lpts in your param file not the wpts ...

What are those points? would you mind sharing a sample DT with its pts just to have an idea ...

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
