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.

positional arguments:

List of files to integrate. Mandatory without GUI

optional arguments:

show this help message and exit
show program's version number and exit
HDF5 File where processed map will be saved. Mandatory without GUI
switch to verbose/debug mode, default: quiet
Prefix or common base for all files
Process all files with this extension
number of points for the fast motion. Mandatory without GUI
number of points for slow motion. Mandatory without GUI
number of points in diffraction powder pattern. Mandatory without GUI
list of dark images to average and subtract (comma separated list)
list of flat images to average and divide (comma separated list)
file containing the mask, no mask by default
file containing the diffraction parameter (poni-file), Mandatory without GUI
do not process the first files
process using OpenCL on GPU
show statistics at the end
Use the Graphical User Interface
Do not use the Graphical User Interface
provide a JSON configuration file

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
