# EEGTCNet

EEGTCNet model from Ingolfsson et al (2020) [ingolfsson2020].

> **Architecture-only repository.** Documents the
> `braindecode.models.EEGTCNet` class. **No pretrained weights are
> distributed here.** Instantiate the model and train it on your own
> data.

## Quick start

```bash
pip install braindecode
```

```python
from braindecode.models import EEGTCNet

model = EEGTCNet(
    n_chans=22,
    sfreq=250,
    input_window_seconds=4.0,
    n_outputs=4,
)
```

The signal-shape arguments above are illustrative defaults — adjust to
match your recording.
