diff_tomo - GUI interface for reduction of diffraction tomography
experiments
usage: diff_map [options] -p ponifile imagefiles* If the
number of files is too large, use double quotes like "*.edf"
Azimuthal integration for diffraction imaging. Diffraction mapping
is an experiment where 2D diffraction patterns are recorded while performing
a 2D scan. Diff_map is a graphical application (based on pyFAI and h5py)
which allows the reduction of this 4D dataset into a 3D dataset containing
the two motion dimensions 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 result file aims at being NeXus
compliant. This tool can be used for diffraction tomography experiment as
well, considering the slow scan direction as the rotation.

Bugs: Many, see hereafter: 1)If the number of files is too large,
use double quotes "*.edf" 2)There is a known bug on Debian7 where
importing a large number of file can take much longer than the integration
itself: consider passing files in the command line
