Note: The Interpreter tab will have '>>>' as a prompt for these commands. It is not necessary to type '>" at the beginning of the line. You should type each line individually and press "Enter" to submit the commands to the Interpreter.
This will result in nodes which are linearly sized and color coded by their GCC, connected by green directed edges, as shown in Figure 5.11 (left). Any numeric node attribute within the network can be used to code the nodes. To view the available attributes, mouse over a node. The GUESS interface supports pan and zoom, node selection, and details on demand. For more information, refer to the GUESS tutorial at http://nwb.slis.indiana.edu/Docs/GettingStartedGUESSNWB.pdf

GUESS supports the repositioning of selected nodes. Multiple nodes can be selected by holding down the 'Shift' key and dragging a box around specific nodes. The final network can be saved via 'GUESS: File > Export Image' and opened in a graphic design program to add a title and legend and to modify label sizes. The image above was modified using Photoshop.

Pruning the network

Pathfinder algorithms take estimates of the proximity's between pairs of items as input and define a network representation of the items that preserves only the most important links. The value of Pathfinder Network Scaling for networks lies in its ability to reduce the number of links in meaningful ways, often resulting in a concise representation of clarified proximity patterns.
