 It downloads a [sample dataset](https://webknossos.org/datasets/scalable_minds/l4_sample_dev/view) with a [sample annotation](https://webknossos.org/annotations/Explorational/6204d2cd010000db0003db91).
 The annotation has been created with "merger mode", where skeleton trees are used to merge segments.

+Read more about the [merger mode in the WEBKNOSSOS documentation](/webknossos/proofreading/merger_mode.html).
 The example then uses the [Dataset API](dataset_usage.md) and [fastremap module](https://github.com/seung-lab/fastremap) for reading, remapping and rewriting the `segmentation` layer.
 
 _This example additionally needs the fastremap package._

 # Annotation File to OME-TIFF
 
-This example shows how to turn a volume annotation downloaded from WEBKNOSSOS into a OME-TIFF. When [manually downloading a WEBKNOSSOS annotation](/webknossos/export.html#data-export-through-the-ui) through the UI you end up with a ZIP file containing the volume segmentation in the WKW-format (and potentially any skeleton annotation).

 As an alternative to manually downloading annotation files, have a look at streaming the data directly from the remote serve, e.g., in [this example](./download_segments.md).
