diffpy.srxplanar 1.0.0rc0

Srxplanar processes data from 2D detectors before propagating it to PDFgetX3

This is part of xPDFsuite package.

diffpy.srxplanar package provides 2D diffraction image integration using non splitting pixel algorithm. And it can estimate and propagate statistic uncertainty of raw counts and integrated intensity.

To learn more about diffpy.srxplanar library, see the examples directory included in this distribution or the API documentation at

For more information about the diffpy.srxplanar library, please consult our online documentation.

Citation

If you use this program to do productive scientific research that leads to publication, we kindly ask that you acknowledge use of the program by citing the following paper in your publication:

Installation

The preferred method is to use Miniconda Python and install from the “conda-forge” channel of Conda packages.

To add “conda-forge” to the conda channels, run the following in a terminal.

conda config --add channels conda-forge

We want to install our packages in a suitable conda environment. The following creates and activates a new environment named diffpy.srxplanar_env

conda create -n diffpy.srxplanar_env diffpy.srxplanar
conda activate diffpy.srxplanar_env

To confirm that the installation was successful, type

python -c "import diffpy.srxplanar; print(diffpy.srxplanar.__version__)"

The output should print the latest version displayed on the badges above.

If the above does not work, you can use pip to download and install the latest release from Python Package Index. To install using pip into your diffpy.srxplanar_env environment, type

pip install diffpy.srxplanar

If you prefer to install from sources, after installing the dependencies, obtain the source archive from GitHub. Once installed, cd into your diffpy.srxplanar directory and run the following

pip install .

This package also provides command-line utilities. To check the software has been installed correctly, type

srxplanar --version

You can also type the following command to verify the installation.

python -c "import diffpy.srxplanar; print(diffpy.srxplanar.__version__)"

To view the basic usage and available commands, type

srxplanar -h

Getting Started

You may consult our online documentation for tutorials and API references.

Support and Contribute

If you see a bug or want to request a feature, please report it as an issue and/or submit a fix as a PR.

Feel free to fork the project. To install diffpy.srxplanar in a development mode, with its sources being directly used by Python rather than copied to a package directory, use the following in the root directory

pip install -e .

To ensure code quality and to prevent accidental commits into the default branch, please set up the use of our pre-commit hooks.

1. Install pre-commit in your working environment by running conda install pre-commit.

2. Initialize pre-commit (one time only) pre-commit install.

Thereafter your code will be linted by black and isort and checked against flake8 before you can commit. If it fails by black or isort, just rerun and it should pass (black and isort will modify the files so should pass after they are modified). If the flake8 test fails please see the error messages and fix them manually before trying to commit again.

Improvements and fixes are always appreciated.

Before contributing, please read our Code of Conduct.
