NAME

diff_tomo - diffraction tomography sinogram construction

DESCRIPTION

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.
