     13We will now open the query workspace for this tutorial. [[BR]]
    1514At the top of the screen, click on the "File" menu and choose "Open File". Alternatively, click on the "Open" toolbar icon [[Image(open_button.png)]]. Navigate to the main VIQUEN directory and select the "tutorial1.mxe" file. Click on it and then click "Open file".

    19 You should now see the following  query workspace.

     22This simple query has 4 operations and consists of a single query block. The "Start" operation indicates the point from which the query will be compiled. Following this, the "Input" operation contains the input data sources for the query. The "Extract Tree" operation then specifies the information that we wish to extract from these input data sources, and the "Output" operation identifies the output graph of this query block. Each of these operations is connected to the next by a directed edge. These edges indicate the next operation in the query-building sequence.
     23
     24We will now examine each of these operations in a little more detail.

     29Click on the "Start" node. The edges of the node will become highlighted to indicate that the node is selected. [[BR]]
     30Click and drag on the "Start" node. This will move the node in the workspace. Note that the edge connected to the "Start" node is automatically updated when the node is moved. [[BR]]
     31Click on the minimize button (-). This will collapse the node. It is a good idea to keep nodes collapsed when you are not working on them since this will prevent accidental modification of the query parameters. [[BR]]
     32Click on the maximize button (+). This will expand the node to its original size.

     34Now try moving, collapsing and expanding the other nodes in the workspace.
