## Overview

AIND behavior utilities provides tools for working with behavioral neuroscience data, including:

- **SyncDataset** — Load and parse HDF5 sync files with automatic label resolution and edge extraction
- **CamstimDataset** — Parse stimulus pickle files and extract frame timing and wheel encoder data
- **Wheel utilities** — Generate QC images and metrics for wheel encoder validation
- **Plotting utilities** — Generic array visualization helpers

## Quick Start

### Loading a sync file

```python
from aind_behavior_utils.sync import SyncDataset

sync = SyncDataset('path/to/sync.h5')
print(sync.label_map)  # View resolved line labels

# Get edge timestamps for a specific line
edges = sync.get_edges('camera', slope='rising')
print(f"Camera edges: {edges}")

# Check for dropped events
dropped = sync.get_dropped_events('vsync', timing_threshold=0.025)
print(f"Dropped vsync events: {dropped}")

sync.close()
```

### Parsing stimulus files

```python
from aind_behavior_utils.stimulus import CamstimDataset

# Load from pickle file
stim = CamstimDataset.from_file('path/to/stimulus.pkl')
print(f"Frame rate: {stim.fps} Hz")
print(f"Total frames: {stim.stim_frame_count}")

# Or load from dict
import pandas as pd
with open('path/to/stimulus.pkl', 'rb') as f:
    pkl_data = pd.read_pickle(f)
stim = CamstimDataset(pkl_data)
```

### Wheel encoder QC

```python
from aind_behavior_utils.stimulus import wheel_utils

# Generate QC images and metrics
images = wheel_utils.calculate_qc_images(stim)
metrics = wheel_utils.calculate_qc_metrics(stim)

print(f"Wheel artifacts: {metrics.get('artifact_count', 0)}")
```

## Dependencies

- **h5py** — HDF5 file I/O
- **numpy** — Array operations
- **pandas** — Data manipulation
- **matplotlib** — Plotting

Zero runtime dependencies for core sync operations beyond the above.

## Installation
To use the software, in the root directory, run
```bash
pip install -e .
```

To develop the code, run
```bash
pip install -e .[dev]
```

## Contributing

### Linters and testing

There are several libraries used to run linters, check documentation, and run tests.

- Please test your changes using the **coverage** library, which will run the tests and log a coverage report:

```bash
coverage run -m unittest discover && coverage report
```

- Use **interrogate** to check that modules, methods, etc. have been documented thoroughly:

```bash
interrogate .
```

- Use **flake8** to check that code is up to standards (no unused imports, etc.):
```bash
flake8 .
```

- Use **black** to automatically format the code into PEP standards:
```bash
black .
```

- Use **isort** to automatically sort import statements:
```bash
isort .
```

### Pull requests

For internal members, please create a branch. For external members, please fork the repository and open a pull request from the fork. We'll primarily use [Angular](https://github.com/angular/angular/blob/main/CONTRIBUTING.md#commit) style for commit messages. Roughly, they should follow the pattern:
```text
<type>(<scope>): <short summary>
```

where scope (optional) describes the packages affected by the code changes and type (mandatory) is one of:

- **build**: Changes that affect build tools or external dependencies (example scopes: pyproject.toml, setup.py)
- **ci**: Changes to our CI configuration files and scripts (examples: .github/workflows/ci.yml)
- **docs**: Documentation only changes
- **feat**: A new feature
- **fix**: A bugfix
- **perf**: A code change that improves performance
- **refactor**: A code change that neither fixes a bug nor adds a feature
- **test**: Adding missing tests or correcting existing tests

### Semantic Release

The table below, from [semantic release](https://github.com/semantic-release/semantic-release), shows which commit message gets you which release type when `semantic-release` runs (using the default configuration):

| Commit message                                                                                                                                                                                   | Release type                                                                                                    |

### Documentation
To generate the rst files source files for documentation, run
```bash
sphinx-apidoc -o docs/source/ src
```
Then to create the documentation HTML files, run
```bash
sphinx-build -b html docs/source/ docs/build/html
```
More info on sphinx installation can be found [here](https://www.sphinx-doc.org/en/master/usage/installation.html).

### Read the Docs Deployment
Note: Private repositories require **Read the Docs for Business** account. The following instructions are for a public repo.

The following are required to import and build documentations on *Read the Docs*:
- A *Read the Docs* user account connected to Github. See [here](https://docs.readthedocs.com/platform/stable/guides/connecting-git-account.html) for more details.
- *Read the Docs* needs elevated permissions to perform certain operations that ensure that the workflow is as smooth as possible, like installing webhooks. If you are not the owner of the repo, you may have to request elevated permissions from the owner/admin. 
- A **.readthedocs.yaml** file in the root directory of the repo. Here is a basic template:
```yaml
# Read the Docs configuration file
# See https://docs.readthedocs.io/en/stable/config-file/v2.html for details

# Required
version: 2

# Set the OS, Python version, and other tools you might need
build:
  os: ubuntu-24.04
  tools:
    python: "3.13"

# Path to a Sphinx configuration file.
sphinx:
  configuration: docs/source/conf.py

# Declare the Python requirements required to build your documentation
python:
  install:
    - method: pip
      path: .
      extra_requirements:
        - dev
```

Here are the steps for building docs in *Read the Docs*. See [here](https://docs.readthedocs.com/platform/stable/intro/add-project.html) for detailed instructions:
- From *Read the Docs* dashboard, click on **Add project**.
- For automatic configuration, select **Configure automatically** and type the name of the repo. A repo with public visibility should appear as you type. 
- Follow the subsequent steps.
- For manual configuration, select **Configure manually** and follow the subsequent steps

Once a project is created successfully, you will be able to configure/modify the project's settings; such as **Default version**, **Default branch** etc.
