Those immunosuppressed, with history of colorectal cancer or inflammatory bowel disease (IBD), were excluded. Patients with symptoms of gastrointestinal infection and colonic inflammation on CT were prospectively included.

Now create a new network from the selection, representing the same final network as earlier.Īgain, this is the same final network as before, with the most connected and most highly disease associated genes.Our objective was to describe the etiologies of acute colitis and to identify patients who require diagnostic endoscopy.

Note that the drop-down at the top is set for Match all (AND) by default, which is what we want in this case.

To add a second filter, click the plus-sign and recreate the disease score filter.

In the Style tab, select the node degree filter from the drop-down.

In the Network tab, select the original network from STRING.

Let's combine the two filters "degree filter" and "disease score" to produce one filter, then apply it to the original network to create a final subnetwork:

Alternatively, you can create a composite filter and apply the logic all at once. If you examine the network you can see several well-known breast cancer oncogenes, for example BRCA1 and ERBB4.īut what if we want to combine these two filters? You could apply them sequentially as individual filters like we did previously, but then you'd need to be careful about the order in which you apply the filters. The resulting network contains much fewer nodes, but they are the most connected and those most highly associated with disease. Again, select File → New Network → From Selected Nodes, All Edges.In the selection slider, select scores between 3.5 and 5.Click the + (add) button and select Column Filter.Enter a name for your filter, for example "disease score". Click on the drop-down to the right and select Create New Filter.The disease score comes from STRING and indicates the strength of the association to the disease queried. To further filter the network, we can prune out nodes with low disease score. The new network will look similar to this:.With the nodes still selected, go to File → New Network → From Selected Nodes, All Edges.We can now create a new network, or subnetwork, from our selected set of nodes. A set of nodes have been selected in your network, highlighted in yellow: At the bottom of the Filter tab, you can see how many edges/nodes where selected. The filter will be automatically applied. This will select all nodes with degree 3 or more. Leave the default selections for the two drop-downs ( In + Out and in), and adjust the slider to include nodes with degree between 3 and 50.Click the + (add) button and select Degree Filter.Enter a name for your filter, for example "node degree". Click on the Filter tab of the Control Panel.

Filtering based on node degree is a useful way to remove nodes with too few or too many connections. Type in "breast cancer" and click Enter to search.Įvery node in a network has a Degree property, which corresponds to the number of edges connecting the node to other nodes, either as a target or source.In the Network Search tool at the top of the Network tab in the Control Panel, select STRING disease query from the drop-down.
