Hi again,

Just to update: I figured out the problem, one of the meta files had a problem (didn't convert back to .vtk) which is weird because no error message was given when I initially converted the .meta file to .vtk! so I excluded that file and StatNonParamTestPDM seems to run without any errors. This is the output I got on the command line:

data has been relabeled: 0 --> group A = 0 ; 1 --> group B = 1
#A: 36, #B: 66
this version does not support writing out covariance ellipsoid stats
tupel: 3 , numFeatures: 3006
group sizes: 36/66 = 102
Features : 3006 , real: 1002
........................................
writing avg shape diff pvalue 0.0077
writing raw pvalues
writing statistic (T^2)
writing T statistic
writing Mean Diff statistic
computing FDR
computing Min distribution


However, now there seems to be another problem! (sorry for so many questions) ... When I want to convert the "meanAll.meta" file to .vtk to visualize I get the error:

CellType required and not defined.
MetaObject: Read: MET_Read Failed
Aborting: No Points in GRID

conversion works fine with meanA and meanB meta file thought! any thought on why?

Thanks,
