       diff_tomo - diffraction tomography sinogram construction


       usage:  diff_tomo  [options]  -p ponifile imagefiles* If the number of files is too large,
       use double quotes like "*.edf"

       Azimuthal integration for diffraction tomography. Diffraction tomography is an  experiment
       where  2D  diffraction patterns are recorded while performing a 2D scan, one (the slowest)
       in rotation around the sample center and the  other  (the  fastest)  along  a  translation
       through  the  sample.  Diff_tomo  is  a  script (based on pyFAI and h5py) which allows the
       reduction of this 4D dataset into a 3D dataset containing the rotations angle  (hundreds),
       the translation step (hundreds) and the many diffraction angles (thousands). The resulting
       dataset can be opened using PyMca roitool where the 1d dataset has to be selected as  last
       dimension.  This  file  is  not  (yet)  NeXus compliant. This tool can be used for mapping
       experiments if one considers the slow scan direction as the rotation.
