NAME¶
diff_tomo - GUI interface for reduction of diffraction tomography experiments
DESCRIPTION¶
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:¶

- -r SLOW, --slow SLOW
- number of points for slow motion. Mandatory without GUI
- -c NPT_RAD, --npt NPT_RAD
- number of points in diffraction powder pattern. Mandatory without GUI
- -d FILE, --dark FILE
- list of dark images to average and subtract (comma separated list)
- -f FILE, --flat FILE
- list of flat images to average and divide (comma separated list)
- -m FILE, --mask FILE
- file containing the mask, no mask by default
- -p FILE, --poni FILE

- --config CONFIG
- 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
