MEDVED: Modulation-Enhanced Diffraction Viewer and EDitor

Information and requirements

_images/medved1.png
MEDVED (Modulation-Enhanced Diffraction Viewer and EDitor) is software that allows a user to load a number of powder patterns (standard two- or three-column ASCII data files) or hkl files (in SHELX format), inspect them separately or together, calculate Fourier transforms (using fast Fourier transform algorithms) and inspect separate harmonics as well as their real or imaginary parts.
If you use this program please cite this paper: Frequency analysis for modulation-enhanced powder diffraction.

Medved is open source software covered by the GPLv3 license.

Source code is freely available at the mercurial repository: https://hg.3lp.cx/medved.

Installation

If you have installed Python 3.6 on your computer, you may install MEDved just using pip:

pip install medved

Beforehand you need to install PyQt5:

pip install PyQt5
On Windows you may need the MS Visual C++ Build Tools 2015 to compile the C-extensions.
