GutenTAG is an extensible tool to generate time series datasets with and without anomalies.
A GutenTAG time series consists of a single (univariate) or multiple (multivariate) channels containing a base oscillation with different anomalies at different positions and of different kinds.

## tl;dr

1. Install GutenTAG from [PyPI](https://pypi.org/project/timeeval-gutenTAG/):

   ```sh
   pip install timeeval-gutenTAG
   ```

   GutenTAG supports Python 3.7, 3.8, 3.9, 3.10, and 3.11; all other [requirements](./requirements.txt) are installed with the pip-call above.

2. Create a generation configuration file [`example-config.yaml`](./generation_configs/example-config.yaml) with the instructions to generate a single time series with two anomalies:
   A _pattern_ anomaly in the middle and an _amplitude_ anomaly at the end of the series.
   You can use the following content:

   ```yaml
   timeseries:
   - name: demo
     length: 1000
     base-oscillations:
     - kind: sine
       frequency: 4.0
       amplitude: 1.0
       variance: 0.05
     anomalies:
     - position: middle
       length: 50
       kinds:
       - kind: pattern
         sinusoid_k: 10.0
     - position: end
       length: 10
       kinds:
       - kind: amplitude
         amplitude_factor: 1.5
   ```

3. Execute GutenTAG with a seed and let it plot the time series:

   ```bash
   gutenTAG --config-yaml example-config.yaml --seed 11 --no-save --plot
   ```

   You should see the following time series:
