Dear Beatriz,

Thank you very much for your reply. 

1) I have tried running SegPostProcess with different parameters. I set sx, sy, and sz to 2, 1, 0.5, 0.1, and 0.01. However, this did not change the outcome. Still, the first binary image did not process, whereas the second binary image processed fine (I think). I was unable to display the "_pp_surfSPHARMMedialMesh.vtk" of the first binary image, regardless of the sx/sy/sz parameters. I was able to display the "_pp_surfSPHARMMedialMesh.vtk" of the second binary image, although the vtk files were all the same (same checksum) regardless of the sx/sy/sz parameters. In addition to the screenshot of "_pp_surfSPHARMMedialMesh.vtk" I have enclosed some images that show the two initial binary images in 3D to give you an idea about the raw data.

2) For the failed GenParaMesh there was no Eurler number text file. For the volume that did proces the number in the Euler text file was 2.

You mentioned I should check the output of segpostprocess. I have displayed most files in the ../Mesh/SPHARM directory and the ones in the Template directory. Except for the "_pp_surfSPHARMMedialMesh.vtk" files in ../Mesh/SPHARM are there any other files of particular interest?

Thanks again for your help.

Best,

Vincent
