| MEDVED (Modulation-Enhanced Diffraction Viewer and EDitor) is software that allows a user to load a number of
  :ref:`powder patterns <medved1>`
  (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 :ref:`real or imaginary parts <medved2>`.

| If you use this program please cite this paper:
  `Frequency analysis for modulation-enhanced powder diffraction <http://dx.doi.org/10.1107/S2053273316008378>`_.

Medved is open source software covered by the GPLv3 license.

Source code is freely available at the git repositories:
    * `https://git.3lp.cx/dyadkin/medved_cpp <https://git.3lp.cx/dyadkin/medved_cpp>`_.

The latest version
^^^^^^^^^^^^^^^^^^^^^

The latest version is `2.2.0 released on 2021.9.21 <https://git.3lp.cx/dyadkin/medved_cpp/releases/tag/v2.2.0>`_.

:download:`Windows x64: medved-2.2.0-win64.zip</_downloads/medved/medved-2.2.0-win64.zip>`

:download:`Linux x64: medved-2.2.0-linux.tgz</_downloads/medved/medved-2.2.0-linux.tgz>`

:download:`MacOS x64: medved-2.2.0-mac.dmg</_downloads/medved/medved-2.2.0-mac.dmg>`

To run Medved in **Windows** you may need to install the the `MS Visual C++ Redistributable
for Visual Studio 2015-2019 <https://aka.ms/vs/16/release/vc_redist.x64.exe>`_.

The **Linux** version of Medved is compiled in Ubuntu 16.04 LTS, thus it should work in any rather
new distributions.
It will probably not work in CentOS or similar "conservative" distributions.

The **MacOS** version of Medved is compiled in the latest MacOS X 10.15.7.
