Description: # Welcome to Use Xponge!
        
        ## Introduction
        
        ``Xponge`` is a lightweight and easy to customize python package to perform pre- and post-processing of molecular simulations.
        
        ### What can Xponge do?
        
        Xponge includes three major categories of functionality, namely, the simulation system construction, simulation data transformation and analysis, and automated workflows for complex simulations. ``Xponge`` is mainly designed for the molecular dynamics (MD) program [SPONGE](https://onlinelibrary.wiley.com/doi/epdf/10.1002/cjoc.202100456)[1], but it can also output some general format files such as mol2 and PDB, so it may help the other molecular modelling programs too.
        
        ## Installation
        
        Xponge can be used on all operating systems (Windows/Linux/MacOS). Some functions (See [here](https://spongemm.cn/xponge_doc/dependency.html#unavalable-functions-on-windows) for the detailed list) to do the quantum chemistry calculations can not be used on Windows because `pyscf` is not available on Windows.
        
        ### 1. pip install
        
        ```bash
        pip install Xponge
        ```
        
        ### 2. source setup
        
        - 2.1 Download or clone the source from the gitee or github repository
        
            The gitee repository is [here](https://gitee.com/gao_hyp_xyj_admin/xponge).
            The github repository is [here](https://github.com/xia-yijie/xponge).
        
                git clone http://gitee.com/gao_hyp_xyj_admin/xponge.git
                git clone http://github.com/xia-yijie/xponge.git
        
        - 2.2 Open the directory where you download or clone the repository
        
        - 2.3 (Optional) Configure the environment
        
            It is recommended to use `conda` to configure the environment. Two `yml` files named `install_requirements.yml` and `extras_requirements.yml` are provided in the repository.
        
            It is recommanded to use the file `install_requirements.yml` to configure the environment. The file will only install the basic dependent packages. If a `ModuleNotFoundError` is raised when you are using `Xponge`, then install the module. This allows you to avoid installing many modules that you will never use, and also makes `Xponge` more cross-platform compatible. Here are the commands to use `install_requirements.yml`.
        
            ```bash
            conda env create -f install_requirements.yml
            conda activate Xponge
            ```
        
            All the dependent packages are listed in the [dependencies](#dependencies) section. If you don't want to install the dependent packages one by one (which can be really annoying), the file `extras_requirements.yml` can help you with the environment configuration except the packages `mindspore` and `mindsponge`. The two packages should be installed according to your device (e.g. whether the backend is CPU, GPU or Huawei Ascend Processors) and can not be simply installed by conda. Here are the commands to use `extras_requirements.yml`.
        
            ```bash
            conda env create -f extras_requirements.yml
            conda activate Xponge
            ```
        
             It is worth noting that `extras_requirements.yml` can not be used on Windows because `pyscf` is not available on Windows.
        
        - 2.4 Run the command
        
            ```bash
            python setup.py install
            ```
        
        ### Installation check
        
        There are some unit tests in ``Xponge``. You can do the basic test to check whether the installation is successful like this:
        
        ```bash
        Xponge test --do base -o test --verbose 1
        ```
        
        Here, ``Xponge`` can be replaced to ``python -m Xponge``, ``python3 -m Xponge`` and so on according to your settings of the environmental variables. Some files will be generated after the test is finished.
        
        ## Quickstart
        
        Here is a simple example.
        
        ```python
        import Xponge
        # Import the force field you need
        import Xponge.forcefield.amber.ff14sb
        # Build the molecule like this
        peptide = ACE + ALA + NME
        # or like this
        peptide2 = NALA + ALA * 10 + CALA
        # or like this
        peptide3 = Xponge.Get_Peptide_From_Sequence("AAAAA")
        # See the documentation for more usage!
        # Save them as your favorite format
        Xponge.save_pdb(peptide, "ala.pdb")
        Xponge.save_mol2(peptide2, "ala12.mol2")
        Xponge.save_sponge_input(peptide3, "ala5")
        ```
        
        Then we can see `ala12.mol2` in VMD:

        Here is another simple example.
        
        ```python
        import Xponge
        import Xponge.forcefield.amber.tip3p
        
        box = Xponge.BlockRegion(0, 0, 0, 60, 60, 60)
        region_1 = Xponge.BlockRegion(0, 0, 20, 20, 20, 40)
        region_2 = Xponge.BlockRegion(0, 0, 40, 20, 20, 60)
        region_3 = Xponge.BlockRegion(0, 0, 0, 20, 20, 20)
        region_4 = Xponge.SphereRegion(20, 10, 30, 10)
        region_5 = Xponge.BlockRegion(20, 0, 20, 60, 60, 60)
        region_2or3 = Xponge.UnionRegion(region_2, region_3)
        region_4and5 = Xponge.IntersectRegion(region_4, region_5)
        t = Xponge.Lattice("bcc", basis_molecule=CL, scale=4)
        t2 = Xponge.Lattice("fcc", basis_molecule=K, scale=3)
        t3 = Xponge.Lattice("sc", basis_molecule=NA, scale=3)
        mol = t.Create(box, region_1)
        mol = t2.create(box, region_2or3, mol)
        mol = t3.create(box, region_4and5, mol)
        Xponge.Save_PDB(mol, "out.pdb")
        ```
        
        Then we can see `out.pdb` in VMD:

        ## Dependencies
        
        `Xponge` does not depend on other packages except numpy for its basic use.
        
        However, there are some complicated functions that depend on some other packages. If you do not install the dependent package, you can not use the related functions.
