Installing the application¶
Recent versions of the Refl1D application are available for windows from github. The file Refl1D-VERSION-exe.zip contains python, the application, the supporting libraries and everything else needed to run the application.
To install, download and extract the zip file. Go to the extracted directory and click on refl1d_gui.bat. This will open a dialog saying that the application is untrusted with a “Don’t run” button at the bottom. Click on “more info” and a “Run anyway” button will appear. For command line operation, open a cmd command terminal, change to the extracted directory and type refl1d.bat.
The installed python is a full version of python. If your specialized reflectometry models need additional python packages, then you can use python -m pip in the extracted directory to install them.
Linux users will need to install from using pip:
pip install refl1d wxpython
Note that the binary versions will lag the release version until the release process is automated. Windows and Mac users may want to install using pip as well to get the version with the latest changes.
Installing from source¶
Installing the application from source requires a working python environment. See below for operating system specific instructions.
Our base scientific python environment contains the following packages as well as their dependencies:
python 3
numpy
scipy
matplotlib
wxpython
Once your environment is in place, you can install directly from PyPI using pip:
pip install refl1d
This will install refl1d, bumps and periodictable.
You can run the program by typing:
python -m refl1d.main
If this fails, then follow the instructions in Contributing Changes to install from the source archive directly.
Windows¶
There are couple of options for setting up a python environment on windows:
python.org, and
With most pypi packages now bundled with wheels, it is now easy to set up a development environment using the official python package. Similarly, anaconda provides binaries for all the refl1d dependencies.
You will need a C/C++ compiler. If you already have Microsoft Visual C installed you are done. If not, you can use the MinGW compiler that is supplied with your python environment or download your own. You can set MinGW as the default compiler by creating the file Libdistutils\distutils.cfg in your python directory (e.g., C:\Python3.8) with the following content:
[build]
compiler=mingw32
Once the python is prepared, you can install the periodic table and bumps package using the Windows console.
Linux¶
Linux distributions will provide the base required packages. You will need to refer to your distribution documentation for details.
On debian/ubuntu, the command will be something like:
sudo apt-get install python3-{matplotlib,numpy,scipy,wxgtk4.0,pyparsing,setuptools}
For development you also want nose and sphinx:
sudo apt-get install python-{nose,sphinx}
Latex is needed to build the pdf documentation.
OS/X¶
Similar to windows, you can install the official python distribution or use Anaconda. You will need to install the Xcode command line utilities to get the compiler.
To run the interactive interface on OS/X you may need to use:
pythonw -m refl1d.main --edit
