Featured Publications tab on your dashboard. There, you find a list of all available public datasets. Click on the dataset name to open the dataset.
Once you are in the view mode, you are presented with three orthongonal views and one 3D viewport. You can use the following shortcuts to navigate the data. See the full list of gestures and keyboard shortcuts for advanced use.
Left Mouse Drag or Arrow Keys
SPACE or Mousewheel
SHIFT + SPACE or Mousewheel
I or ALT + Mousewheel
O or ALT + Mousewheel
Scroll Mousewheel (3D View)
Zoom In And Out
Right Click Drag (3D View)
Rotate 3D View
Toggle Viewport Maximization
You can also change the size of the viewports to see more details in your data and customize your layout.
Create Tracing button from the view mode of a dataset to create your first annotation. webKnossos will launch the main annotation screen allowing you to navigate your dataset and place markers to reconstruct skeletons.
Drag the mouse while pressing the left mouse button to navigate the dataset. Right-click in the data to place markers, called nodes. Basic movement in the dataset is done with the mouse wheel or by pressing the spacebar keyboard shortcut.
Learn more about the skeleton, volume, and hybrid annotations as well as the interface in the Tracing UI guide.
