Welcome to DPDAK
DPDAK is an open source (GPL) tool developed for (online) analysis of large sequences of small angle scattering data - but can be used for other data as well. It is written in Python and runs on Windows and Linux. The development is a cooperation between DESY and MPIKG.
The latest release is 1.4.1:
- Because of memory error in python pyFAI module (since version 0.11.0) for 32-bit machine, we release only 64-bit Windows version.
- Windows version:
Supported Operating System:
- Windows 7, Windows 10
- Microsoft Visual C++ 2008 SP1 Redistributable Package (x86, x64)
Microsoft Visual C++ Compiler for Python 2.7
- Microsoft .NET Framework 3.5for 32-bit machine required also:
- Microsoft Visual C++ 2005 Redistributable Package (x86)
- Microsoft Visual C++ 2010 Redistributable Package (x86)
- 2 GHz or faster processor
- At least 2 GB of RAM; Recommend 4 GB RAM or higher
- 670 MB of available hard disk space
Download Windows version as zip-file: dpdak_win64bit_v1_4_1.zip
- Linux version:
The Linux installation is just from source. To use the source package of dpdak you need to install the free Python programming language and some additional libraries.
Most Linux systems have Python installed by default.
The current version of dpdak needs the following Python version and packages:
Please make sure to choose the correct package versions for your Python installation, e.g. if you installed Python 2.7.11 32-bit you need to install all packages in their 2.7 version for 32-bit as well.
Download Linux version as zip-file: dpdak_Linux_v1_4_1.zip
