Project description
EXAFS Neo
Versions: 2.0.8
Last update: May 1, 2024
EXAFS Neo utilize Genetic algorithm in fitting Extended X-ray absorption fine structure(EXAFS).
Prerequisites
It is highly recommend to utilize anaconda
or pip
package managers to prevent unforeseen dependency conflicts. EXAFS Neo uses larch
to process the x-ray spectrum.
- Python: => 3.9
- Numpy: => 1.20
- Scipy: => 1.6
- Larch: > 0.9.47
- Matplotlib: > 3.0
It is highly recommend to create a new environment in anaconda
to run EXAFS Neo to prevent packages conflicts. For Windows
operating system, if you encounter an issue requiring "Microsoft C++ 14.0 or greater is needed", please download the tools at the following location C++ Tools
and make sure to select C++ build tools during installation process.
if you are on a Mac (either Intel or M1), you need to make sure that xcode command line tools is install, if not input this command into terminal:
xcode-select --install
Dependencies
EXAFS Neo requires the following dependencies to run:
Notes: this step below is only needed if you are installing using source code
# Create new anaconda environment
conda create -y --name exafs python=>3.9.10
conda activate exafs
conda install -y -c conda-forge "numpy>=1.23" "scipy>=1.8" "matplotlib>=3.6" "h5py>=3.5" "wxpython>=4.1" scikit-image scikit-learn pycifrw pandas jupyter plotly pyparsing pytest pytest-cov coverage
pip install lmfit peakutils pyepics pyshortcuts termcolor sphinx dill pycifrw xraydb wxmplot wxutils fabio silx imageio charset-normalizer
pip install xraylarch
Installations
To install via PIP:
conda create --name "exafs_neo" "python=3.12"
conda activate exafs_neo
pip install exafs_neo
To install EXAFS Neo, simply clone the repo:
git clone https://github.com/laumiulun/EXAFS_Neo.git
cd EXAFS_Neo/
pip install .
Usage
To run the included test suite, use the following command:
./run_tests
To run a sample test, make sure the environment is set correctly, and select an input file:
exafs_neo -i test_inputs/test_temp.ini
Alternatively, you can also run EXAFS Neo in a jupyter notebook, please follow the example in the example/jupyter folder
GUI
We also have provided a GUI for use in additions to our program, with additional helper script to facilitate post-analysis. To use the GUI:
exafs_neo_gui
The datafile requires header contain at least either a combination of (k, chi) or (energy, mu). It also requires a minimum of one newline for it to work correctly. An example of the correct header is as follows:
#---------------------------------------------------------------------
# k chi chik chik2 chik3 win energy
Self adsorption correction
EXAFS also provides an internal option to perform self-adsorption on the sample file using Booth et al. correction. This is performed using git submodules:
git submodule update --init --recursive
cd contrib/sabcor/
make
Update
EXAFS Neo is under active development, to update the code after pulling from the repository:
git pull --rebase
python setup.py install
Video Demonstrations
You can see a list of video demonstrations of the EXAFS Neo package presented, future presentation related to this software will be posted as they are available
