Citation: A customizable software for fast reduction and analysis of large X-ray scattering data sets: applications of the new DPDAK package to small angle X-ray scattering and grazing-incidence small angle X-ray scattering, Benecke, G. et al., J. Appl. Cryst. 47, 1797-1803, (2014), doi:10.1107/S1600576714019773.

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.

Using dpdak¶

To set the environment use the module command

xwhich dpdak

 Provided by module(s)
