'''take amd64 the win32 bit versions if you have a computer with 64 bit.'''

== Install python and necessary packages ==

=== Winpython ===

Make a folder: '''C:\WinPython27'''.<br>Run the downloaded winpython exe file, and extract for example to: '''C:\WinPython27'''.<br>Open '''WinPython Control Panel''' in ex. '''C:\WinPython27\WinPython-64bit32bit-2.7.4.1x'''<br>

For a command window, use the '''WinPython Command Prompt''' found in '''C:\WinPython27\WinPython-64bit32bit-2.7.4.1x''', which fixes path issues for finding python.

==== Trick to set variables in cmd ====Make a folder '''own''' in '''C:\WinPython27\WinPython-32bit-2.7.x\scripts''' and <br>copy '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\env.bat''' to '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\own\pyt32.bat'''<br>and copy '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\cmd.bat''' to '''C:\WinPython27\WinPython-32bit-2.7.x\scripts\own\cmdpyt32.bat'''<br> Modify '''pyt32.bat''' from<source lang="python">set WINPYDIR=%~dp0..\python-2.7.5</source>to include '''..\'''<source lang="python">set WINPYDIR=%~dp0..\..\python-2.7.5</source> Modify '''cmdpyt32.bat''' from<source lang="python">call %~dp0env.bat</source>to<source lang="python">call %~dp0pyt32.bat</source> ==== Trick to add .bat files to PATH ====If you have permission to change the Environment Variables in windows, you can add the '''pyt32.bat''' and '''cmdpyt32.bat''' to your path.<br>Right click Computer -> properties -> Advanced system settings -> Environment Variables -> User variables -> Edit: PATH <br>Add to end of the Variable value: ;C:\WinPython27\WinPython-32bit-2.7.x\scripts\ownIn any folder, hold "Shift" and right click, "Open command window here". Write:<source lang="powershell">pyt32python</source> == Install Visual Studio Express 2012 for Windows Desktop ==

 For 64 32 bit compiling, you will only need, '''Visual Studio ProfessionalExpress for Windows Desktop''', since it has: 64-bit x64 compiler.<br>From http://www.microsoft.com/visualstudio/eng/downloads, download and install: [http://go.microsoft.com/?linkid=9810223 9816758 Visual Studio Professional 2012 90-day trialExpress for Windows Desktop].<br>

== Bugfix scons for 32bit building - ONLY do this if you have winpython 32 bit. ==Due to a bug, versions of scons '''<=2.3''' should alter a line in:<br>'''C:\WinPython27\WinPython-32bit-2.7.4.1\python-2.7.4\Lib\site-packages\scons-2.3.0\SCons\Tool\MSCommonvc.py''' Line '''364''': if not req_target_platform and target_platform in ('amd64','x86_64'):Should be: if target_platform in ('amd64','x86_64'): = Install Subversion checkout of relax =={{historical svn}}

Right click in winpython folder: '''C:\WinPython27\WinPython-64bit-2.7.4.1''', and select '''SVN Checkout'''. Write the path: svn://svn.gna.org/svn/relax/trunk svn://svn.gna.org/svn/relax/branches/relax_disprelax_trunk

== Build relax ==

Navigate to the SVN checked out relax folder.<br> cd C:\WinPython27\relax_trunk_32 scons

Or navigate to C:\WinPython27\relax_trunk_32, hold "Shift" and right click, "Open command window here". Write: cd ..\relaxpyt32

=== Modify relaxpyt32.bat ===Copy relaxModify '''C:\WinPython27\WinPython-32bit-xxx\scripts\own\pyt32.bat ''', and add to relaxgui.batend of file<source lang="powershell">set PATH=%PATH%;C:\WinPython27\relax_trunk_32</source>

Modify relax.batTest installation, by clicking '''C: 32x: %~dp0\..WinPython27\pythonWinPython-32bit-2.7.4xxx\scripts\python "%~dp0own\relaxcmdpyt32.pybat''', and write<source lang="powershell" %*>relax 64x: %~dp0\..\pythonrelax -2.7.4.amd64\python "%~dp0\relax.py" %*g</source>

Modify relaxgui==== Tip - shortcut to cmdpyt32.bat====Make shortcut to '''C:\WinPython27\WinPython-32bit-xxx\scripts\own\cmdpyt32.bat''', and modify the shortcut. Set 32x'''Start in: ''' %~dp0\PWD%You can now copy this shortcut around, which open a command prompt at the current folder, and set the paths correctly. == Install other software ===== xmgrace - for the plotting results of NMR-relax ===relax produces xmgrace "'.agr" files for plotting.
