[3dem] different mrc formats in relion-1.2 and xmipp-3. ???

      I noticed that (at least) some (or all?) of the routines of relion 
and xmipp output different mrc-formats as revealed with 
"xmipp_image_header".  For example, a file created with xmipp (e.g. a 
with "xmipp_phantom_create")  has "Dimensions     : 1 x 244 x 244 x 244  
((N)Objects x (Z)Slices x (Y)Rows x (X)Columns)" whereas files created 
with relion have  "Dimensions     : 244 x 1 x 244 x 244  ((N)Objects x 
(Z)Slices x (Y)Rows x (X)Columns)". When trying to work on a file like 
the latter with xmipp I get an error message (e.g in "in 
xmipp_transform_symmetrize" like
  " _ERROR 3:  Argument missing
The symmetry order is not valid for images
File: libraries/reconstruction/symmetrize.cpp line: 161"

What is wrong? Is there a way of easily fix this?

  Thanks for hints, Dieter
