Its not possible to choose MetaImage_* from any menus in the
calculator. From the "attribute mode" drop down menu I can choose:

Point data
cell data

If  I manullay type:

MetaImage_0*iHat + MetaImage_1*jHat +  0*kHat

into the expression editor and press apply I just get a bunch of error:

ERROR: In ..\..\..\src\VTK\Common\vtkFunctionParser.cxx, line 1505
vtkFunctionParser (0DB26B70): Syntax error: expecting a variable name;
see position 0


ERROR: In ..\..\..\src\VTK\Common\vtkFunctionParser.cxx, line 1505
vtkFunctionParser (0DB26B70): Syntax error: expecting a variable name;
see position 0


Warning: In ..\..\..\src\VTK\Graphics\vtkArrayCalculator.cxx, line 394
vtkArrayCalculator (0DFAE8D0): An error occured when parsing the
calculator's function.  See previous errors.




If I select my .mhd file I can see that MetaImage is selected in the
top menu (its not possible to select anything else).

I am using version 3.6.1 on windows.

Any ideas are most welcome!
