Hi, 

I'm currently planning to do a hippocampal shape analysis. After trying to use 3Dslicer I decided it might be easier to use the command line functions. I managed all steps except I now am stuck using StatNonParamTest. 

For some reason it fails at reading in the files, it seems to confuse the .vtk file with the group information.
This is the command I used:

StatNonParamTestPDM list.txt -surfList -numPerms 1000 -signLevel 0.05 -signSteps 1000 -v

It produced the following output:

/home/memory/nilmul/ShaTut/out/Mesh/Para/groupA_01_hippo_ppSPHARM.vtk 0 1
/home/memory/nilmul/ShaTut/out/Mesh/Para/groupA_02_hippo_ppSPHARM.vtk 0 1
/home/memory/nilmul/ShaTut/out/Mesh/Para/groupB_01_hippo_ppSPHARM.vtk 1 1
/home/memory/nilmul/ShaTut/out/Mesh/Para/groupB_02_hippo_ppSPHARM.vtk 1 1

Error reading meshfile: /home/memory/nilmul/ShaTut/out/Mesh/Para/groupA_01_hippo_ppSPHARM.vtk
ITK error: itk::ERROR: SpatialObjectReader(0x184bba0): No groups were found in file /home/memory/nilmul/ShaTut/out/Mesh/Para/groupA_01_hippo_ppSPHARM.vtk

I attached the list.txt file.

I used the latest version of SPHARM-PDM (1.13) and the latest version of StatNonParamTestPDM as well.

Any help would be greatly appreciated!

Best regards,
Nils
