Hi Beatriz,

Using the individual commands, I still encounter error when using GenParaMesh.

My initial input file is: groupA_01_hippo.gipl.gz

This is what I did:

SegPostProcessCLP --echo --label 1 groupA_01_hippo.gipl.gz test.gipl.gz

GenParaMeshCLP test.gipl.gz --iter 800 --label 1
(Parse Error: One or more required arguments missing) so I added in the output file names

GenParaMeshCLP --iter 800 --label 1 test.gipl.gz test_para test_surf

itk::ExceptionObject (0x7fffa2db06e0)
Location: "Unknown"
File: /home/lucileb/spharm-pdm/Libraries/Shape/Algorithms/BinaryMask3DEqualAreaParametricMeshSource.txx
Line: 95
Description: BinaryMask3DEqualAreaParametricMeshSource : Image empty

I am not sure if this is the reason why the GenParaMesh module fails in Slicer as well. I am using the newest spharm-pdm package that Lucile B. uploaded.

Thanks,
Sylvia
