# Initiating Computation

Once all the Dicoms corresponding to a particular series are uploaded, the computation can be triggered.

{% hint style="info" %}
**Attention**:

Perform the computation call only for qER and qCT use cases.

Use the following sample script to initiate processing.

{% code title="Python" overflow="wrap" %}

```python
# Make the HTTP Get request to the service
r = requests.get(URL, headers={'Authorization': 'Token {}'.format(TOKEN)})
```

{% endcode %}
