behavelet: a wavelet transform for mapping behavior
============

</p>
behavelet is a Python implementation of the normalized Morlet wavelet transform for behavioral mapping from [Berman et al. (2014)](https://doi.org/10.1098/rsif.2014.0672).
It runs on the CPU using numpy and multiprocessing or on the GPU using [CuPy](https://github.com/cupy/cupy).
This code was adapted to Python using [the original MotionMapper code](https://github.com/gordonberman/MotionMapper) from Gordon Berman et al.
Quick Start
------------
Here is an example of how to use behavelet on the CPU with a randomly generated dataset:
```python
from behavelet import wavelet_transform
import numpy as np
n_samples = 10000
n_features = 10
X = np.random.normal(size=(n_samples, n_features))
freqs, power, X_new = wavelet_transform(X, n_freqs=25, fsample=100., fmin=1., fmax=50.)
```
use the `n_jobs` argument to parallelize the computations across multiple threads:
```python
freqs, power, X_new = wavelet_transform(X, n_freqs=25, fsample=100., fmin=1., fmax=50., n_jobs=-1)
```
and use the `gpu` argument to run it on the GPU with [CuPy](https://github.com/cupy/cupy):
```python
freqs, power, X_new = wavelet_transform(X, n_freqs=25, fsample=100., fmin=1., fmax=50., gpu=True)
```
- `freqs` is a `(n_freqs,)` shaped array of the frequencies used for the wavelet transform
- `power` is a `(n_samples,)` shaped array with the total power for the wavelet coefficients in each sample
- `X_new` is a `(n_samples, n_freqs*n_features)` shaped array of the wavelet coefficients.

Installation
------------
Install the latest stable version with pip:
```bash
pip install behavelet
```
Install the development version with pip:
```bash
pip install git+https://www.github.com/jgraving/behavelet.git
```
You can also install from within Python rather than using the command line, either from within Jupyter or another IDE, to ensure it is installed in the correct working environment:
```python
import sys
!{sys.executable} -m pip install git+https://www.github.com/jgraving/behavelet.git
```
If you wish to use the GPU version, you must [install CuPy manually](https://github.com/cupy/cupy#installation).
Development
-------------
Please submit bugs or feature requests to the [GitHub issue tracker](https://github.com/jgraving/behavelet/issues/new). Please limit reported issues to the behavelet codebase and provide as much detail as you can with a minimal working example if possible.
If you experience problems with [CuPy](https://github.com/cupy/cupy), such as installing CUDA or other dependencies, then please direct issues to their development team.
