# PyQAlloy-compatible Model for D Parameter prediction based on Hu2021

Release: ![PyPI](https://img.shields.io/pypi/v/pqam-dparamhu2021)

Compatible with: [![PyPI - Python Version](https://img.shields.io/pypi/pyversions/pqam-dparamhu2021)](https://pypi.org/project/pqam-dparamhu2021)

Tests: [![small runtime test](https://github.com/amkrajewski/pqam-dparamhu2021/actions/workflows/runtimeTest.yml/badge.svg)](https://github.com/amkrajewski/pqam-dparamhu2021/actions/workflows/runtimeTest.yml)

This repository contains a PyQAlloy-compatible compositionalModel, compatible with [ULTERA Database (ultera.org)](https://ultera.org) infrastructure, for D Parameter Prediction Based on [Yong-Jie Hu 2021 (10.1016/j.actamat.2021.116800)](https://doi.org/10.1016/j.actamat.2021.116800) that 
accepts a chemical formula string of an alloy or a `pymatgen.Composition` object. It return:

Output Order: [`gfse`, `surf`, `dparam`]

Output Meaning (all based on [10.1016/j.actamat.2021.116800](https://doi.org/10.1016/j.actamat.2021.116800)):
- `gfse` - Genralized Stacking Fault Energy (GSF) [J/m^2]
- `surf` - Surface Energy (Surf) [J/m^2]
- `dparam` - D Parameter [unitless] calculated as `surf/gfse`

> Note: The predicted energy is actually the _Unstable_ Stacking Fault Energy, which is the value of GSFE at a spacific high point, but we keep the naming scheme by the original model authors.

## Install and use

To run this model you will need **Python 3.9+** and **R 4.1.0+** installed on your system, ideally **before** you install
this software. For Python, we recommend you use a virtual Conda environment, which chan be created with minimal effort 
(see [Miniconda install instructions](https://docs.conda.io/en/latest/miniconda.html)). For R, it can be downloaded 
pre-compiled from a _Comprehensive R Archive Network_ repository (e.g. [Case CRAN](https://cran.case.edu)) and should 
work on most systems, including ARM-based (e.g. Apple M1).

If you have Python and R, you can simply install this model with:
    
    pip install pqam_dparamhu2021

Then, use should be as simple as:

    import pqam_dparamhu2021
    
    print(pqam_dparamhu2021.predict("W30 Mo25 Ta45"))

***

In some cases, required `locfit` R package may not be installed automatically. If you get an error message about it,
try to go to your R console, typically by typing `R` in your terminal, and install it manually with:

    install.packages("locfit")

Or, if you are automating things and need a single-liner, on Mac OS and Linux, the following should work:

    Rscript -e "install.packages('locfit', repos='http://cran.us.r-project.org')"

## Hu's README File

>Hello, thank you for your interest in our work!
>Here we provide a script written in R language to take an alloy composition of interest and correspondingly predict the GSF energy, surface energy, and the >ductility parameter based on the SL models in our manuscript ( https://doi.org/10.1016/j.actamat.2021.116800)
>To run the script and make predictions, you need to:
>1)	Download the RStudio platform. (https://www.rstudio.com/) ## No worry, it is open access 😊
>2)	Put all the files you downloaded from Materials Commons (basically all our files) into one local folder
>3)	Open the “predict.R” file in RStudio, input the alloy composition there, execute every line there, and the prediction will jump out in the console window >below. 
>
>Please contact qiliang@umich.edu or yh593@drexel.edu if you have any questions. 
>
>P.S.,
>“predict_screen_4nary_all.csv” is the original data for plotting Figure 7&8 in the manuscript. Other figures in the manuscript can be reproduced by the data >listed in the tables in the manuscript.
