DRDMannTurb (short for *Deep Rapid Distortion Theory Mann Turbulence model*) is a data-driven framework
for synthetic turbulence generation in Python.
The code is based on the original work of Jacob Mann in [1994](https://doi.org/10.1017/S0022112094001886) and [1998](https://doi.org/10.1016/S0266-8920(97)00036-2)
as well as in the deep-learning enhancement developed by Keith et al. in [this 2021 publication](https://arxiv.org/pdf/2107.11046.pdf).

## Installation

Pre-compiled wheels for the package are available via ``pip install drdmannturb``.
See our [development environment instructions](#development-version-installation-instructions)
for instructions on installing development versions.

> [!NOTE]
> `DRDMannTurb` requires the `FFTW` library to be installed on your system for the `pyFFTW` dependency. Please install it using your system's package manager (e.g., `brew install fftw` on macOS, `sudo apt-get install libfftw3-dev` on Debian/Ubuntu) before installing `DRDMannTurb`.

## Basic Usage

See the ``/examples/`` folder for baselines from the paper and for examples of the many functionalities of the package. These examples are rendered in a more readable
format on our documentation [here](https://methods-group.github.io/DRDMannTurb/examples.html) also.

DRDMannTurb consists of two primary submodules ``spectra_fitting`` and ``fluctuation_generation``
which are respectively focused on fitting a Deep Rapid Distortion (DRD) model and
on generating synthetic turbulence "boxes" with a fit DRD model.

## Questions?

If you have any questions, the best way to receive help is by creating a thread in our Discussions or by contacting the authors (Alexey Izmailov, Matthew Meeker) by email directly. If your question pertains to a problem with the package, please open an Issue so that it can addressed.

See also the below instructions for installing DRDMannTurb for development purposes.

### Development Version Installation Instructions

To set up a development environment, we recommend using [`uv`](https://github.com/astral-sh/uv), a fast Python package installer and resolver.

1.  **Install `uv`**: Follow the official [`uv` installation instructions](https://github.com/astral-sh/uv#installation).
2.  **Install System Dependencies**: Ensure the `FFTW` library is installed (see [Installation](#installation) section above).
3.  **Install Python**: Make sure you have Python >= 3.9.16 installed and available. We recommend using a Python version manager like [`pyenv`](https://github.com/pyenv/pyenv).
4.  **Clone the Repository**: `git clone https://github.com/METHODS-Group/DRDMannTurb.git && cd DRDMannTurb`
5.  **Create and Activate Virtual Environment**:
    ```bash
    # Create a virtual environment using your installed Python
    uv venv
    # Alternatively, you can explicitly set the Python version with the following
    uv venv --python 3.9.16
    # Activate the environment (syntax may vary slightly for different shells)
    source .venv/bin/activate
    ```
6.  **Install in Editable Mode with Dependencies**: Install the package in editable mode along with development and documentation dependencies. *Make sure to quote the argument containing brackets.*
    ```bash
    # Install core, docs, and dev dependencies
    uv pip install -e '.[docs,dev]'
    ```

We also ask that you install our
``pre-commit`` configuration by running ``pre-commit install`` in the root directory
of this repository. If you are unfamiliar with ``pre-commit``,
the documentation can be found [here](https://pre-commit.com/).

### Running Tests Locally

DRDMannTurb's test suite is built with [Pytest](https://docs.pytest.org/en/stable/). Running the tests locally can be done by running `pytest`
from the project root.

Tests decorated with `slow` can be run with the `--runslow` flag; they are otherwise skipped. Note that several of these tests require (at least
``partially'') training a DRD model, and so the suite may take several minutes to complete.
Note also that certain components of the test suite require CUDA; these are also
skipped if a CUDA device is not available.

### Local Documentation Building Instructions

Our documentation source lives in the ``/docs/`` folder.
Ensure you have installed the necessary dependencies by including the `docs` extra during installation (`uv pip install -e '.[docs,dev]'`).

Running ``make html`` from the `docs` directory will generate html pages in the ``/docs/build/html`` folder; these can be hosted locally with ``python -m http.server <PORT-NUMBER>``.
