xrayutilities 1.3.3

package for x-ray diffraction data evaluation

xrayutilities

[![Build Status](https://travis-ci.org/dkriegner/xrayutilities.svg?branch=master)](https://travis-ci.org/dkriegner/xrayutilities)

xrayutilities is a collection of scripts used to analyze x-ray diffraction data. It consists of a Python package and several routines coded in C. It is especially useful for the reciprocal space conversion of diffraction data taken with linear and area detectors.

Contents

  • examples: directory with example scripts and configurations
  • xrayutilities: directory with the sources for the Python package
  • tests: directory with the unittest scripts
  • setup.py: distutils install script used for the package installation
  • xrayutilities.pdf: pdf-file with documentation of the package

Installation

Installing xrayutilities is an easy process done by executing

python setup.py install

or

python setup.py install –prefix=<install_path>

in the source folder of xrayutilities on the command line/terminal. The first command installs in the systems default directories, whereas in the second command you can manually specify the installation path.

By default the setup.py script tries to use OpenMP. If you do not want to use OpenMP or do not have it available use the –without-openmp option for the installation:

python setup.py –without-openmp install –prefix=<install_path>

Requirements

The following requirements are needed for installing and using xrayutilities:

  • Python (version 2.7 or >= 3.2)
  • C-compiler (preferential with OpenMP support)
  • h5py
  • scipy (version >= 0.13.0)
  • numpy (version >= 1.8)
  • lmfit (optionally)
  • matplotlib (optionally)
  • unittest2 (optionally - only if you want to run the tests)
  • numpydoc (optionally - only when you want to build the documentation)

refer to your operating system documentation to find out how to install those packages. On Microsoft Windows refer to the Documentation for the easiest way of the installation (Python(x,y) or WinPython).

Python-2.7 and Python-3.X compatibility

The current developement focuses on Python-3.X and we ask all users to update to Python-3 if possible, however, xrayutilies can be used with Python-2.7 as well. Care was taken to make this possible from the same code-base.

The Python package configuration

The following steps should only be necessary for user local installation to ensure the Python module is found by the Python interpreter: In this case the module is installed under <prefix>/lib[64]/python?.?/site-packages on Unix systems and <prefix>/Lib/site-packages on Windows systems.

If you have installed the Python package in a directory unknown to your local Python distribution, you have to tell Python where to look for the Package. There are several ways how to do this:

  • add the directory where the package is installed to your PYTHONPATH environment variable.

  • add the path to sys.path in the .pythonrc file placed in your home directory

    import sys sys.path.append(“path to the xrayutilities package”)

  • simply apply the previous method in every script where you want to use the xrayutilities package before importing the package

    import sys sys.path.append(“path to the xrayutilities package”) import xrayutilities

Obtaining the source code

The sources are hosted on sourceforge in git repository. Use

git clone git://git.code.sf.net/p/xrayutilities/code xrayutilities

to clone the git repository. If you would like to have commit rights contact one of the administrators.

Update

if you already installed xrayutilities you can update it by navigating into its source folder and obtain the new sources by

git pull

or download the new tarball from sourceforge (http://sf.net/projects/xrayutilities) if any code changed during the update you need to reinstall the Python package. To determine the path in which xrayutilities where installed previously use

python -c “import xrayutilities as xu; print xu.__file__”
/usr/local/lib64/python2.7/site-packages/xrayutilities/__init__.pyc

if the output is e.g.: /usr/local/lib64/python2.7/site-packages/xrayutilities/__init__.py you previously installed xrayutilities in /usr/local, which should be used again as install path. Use

python setup.py install --prefix=<path to install directory>

to install the updated package.

Documentation

Documention for xrayutilities is found in the xrayutilities.pdf file or on the webpage http://xrayutilities.sourceforge.net

The API-documentation can also be browsed by

pydoc -p PORT

in any web-browser, after the installation is finished.

To build the PDF documentation from the docu-sources use:

python setup.py build build_doc -b pdf

You will need sphinx, numpydoc and rst2pdf.

Or generate a texinfo file using

python setup.py build_doc -b texinfo cd build/sphinx/texinfo; make

Packaging

create a tarball for redistribution of xrayutilities without the use of git

python setup.py sdist

creates a tarball in the directory dist, which contains everything needed for the installation of xrayutilities
