Dear Martin,
thanks ... former problem solved. However it  went wrong again with this message:

MetaObject: Read: MET_Read Failed
reading Mesh /home/olof/Desktop/SPHARM_DOCS/HC_L_amyloid/Mesh/SPHARM/12847241-39ef-437e-9454-ee79a7168244_hippocampus_left_roi_pp_surfSPHARM_procalign.vtk - .vtk
CellType required and not defined.

I did not see any problem in the shape analysis module - and I have my post-processed files. 

So what is causing this problem?

best
Olof
