It is known to run on Windows, Mac and Linux. For optimal usage on a windows machine it should be run with 64 bit python.

The easiest way to obtain almost all required packages is to install WinPython 64 bit or the Anaconda 64 bit python distribution. After the installation you need to install pyFAI, fabio and pyqtgraph. Please refer to the links above for their respective installation instructions. For 64 bit compilation of the c-code in pyFAI and fabio the easiest available compilers are either included in Visual Studio (not the express edition), the Windows Software Development Kit version 7.1 (http://msdn.microsoft.com/en-us/windowsserver/bb980924.aspx) or the Microsoft Visual C++ Compiler for Python 2.7 (http://www.microsoft.com/en-us/download/details.aspx?id=44266).

Python and the other required packages can be installed by using a package manager like macports. For pyFAI, fabio, and pyqtgraph please refer to their installation instructions. (Please note to install pyFAI on Mac you have to use the gcc compiler, therefore use: sudo CC=gcc python setup.py install for the installation and please make sure that gcc is not linked to clang, before...)

Except for pyFAI, fabio and and pyqtgraph all packeges can be installed using the normal package manager (e.g. apt-get or pip). The installation for the other 3 modules is described on their respective website. The installation should be straight forward as on Linux gcc is the standard compiler.

You can start the program by running the Dioptas.py script in the Dioptas_main folder.
