Python tools for Nano-structures Crystallography (Scripts)

PyNX stands for *Python tools for Nano-structures Crystallography*. It is a python library with the following main modules:

1) pynx.scattering: *X-ray scattering computing using graphical processing units*, allowing up to 2.5x10^11 reflections/atoms/seconds (single nVidia Titan X). The sub-module``pynx.scattering.gid`` can be used for *Grazing Incidence Diffraction* calculations, using the Distorted Wave Born Approximation

2) pynx.ptycho : simulation and analysis of experiments using the *ptychography* technique, using either CPU (deprecated) or GPU using OpenCL. Examples are available in the pynx/Examples directory. Scripts for analysis of raw data from beamlines are also available, as well as using or producing ptychography data sets in CXI (Coherent X-ray Imaging) format.

3) pynx.wavefront: *X-ray wavefront propagation* in the near, far field, or continuous (examples available at the end of ``wavefront.py``). Also provided are sub-modules for Fresnel propagation and simulation of the illumination from a Fresnel Zone Plate, both using OpenCL for high performance computing.

4) pynx.cdi: *Coherent Diffraction Imaging* reconstruction algorithms using GPU.

In addition, it includes :doc:`scripts <scripts/index>` for command-line processing of ptychography data from generic CXI data (pynx-ptycho-cxi) or specific to beamlines (pynx-ptycho-id01, pynx-ptycho-id13,...).
