This section shows how to get started by walking through the main functionalities available in the Simmune NetworkViewer software using a simple example model (G_proteins_legacy_version.dbf).
Start the "Simmune NetworkViewer"

Open an existing model file
Click the "File" menu and select the "Open
File..." menu item. When a file dialog prompts the user to
choose a model file, select the example model file and click the
"Open" button.

Shortly after the network construction, the network panel on the
right shows the whole network as an overview. In the tree panel, the
numbers "8" and "22" enclosed in the
parentheses following "Species" and
"Complex" indicate that there are 8 complex species and
22 complexes in the model. The number "4" enclosed in the
parentheses after the item "Receptor" indicates that 4
complexes belong to the complex species "Receptor".
Similarly, the reaction rule panel shows that the model consists of
"11" rules -- 3 associations, 6 dissociations, and 2
transformations.
Edge color depends on the reaction type. The default colors for complex association, complex dissociation, and complex transformation are green, orange, and purple respectively. You may set arbitrary color by configuring appearance.
An edge representing an association or a dissociation points to the mediating binding site on the complex species node. An edge representing a transformation points to the middle of the complex species node since transformations do not involve particular binding sites (except for transformations that induce intra-complex bond formations or dissociations).

Zoom in/out and panning with mouse
In the network panel, scroll mouse up/down to zoom in/out. You
may also click the icon on the toolbar,
for zoom in and
for zoom out. Drag mouse to pan the network in
any direction.
The zooming factor is limited.
Zooming scales the network panel uniformly. To enlarge/shrink only a particular type of components (e.g. nodes, edges, or text labels), you may customize the appearance for each type of component.

To display the whole network in the network panel, click the
"View" menu and select the "Fit to screen"
menu item or simply click the icon
on the toolbar.
Show the network legend
Click the "View" menu and check the "Show
legend" menu item to display the legend of the icons used in
the network panel. Uncheck it to hide the legend. Another way to
show/hide the legend is by checking/unchecking the item "Show
legend" in the context menu of the network panel.
Here, three complex species are shown: "Ligand",
"Receptor", and "Ligated Receptor". There
are two reactions, one association and one dissociation, that involve
the three complex species.

Select a complex species
Click the complex species node "Receptor" to select
the complex species "Receptor". Edges are highlighted to
show that 5 reaction rules, 1 association and 4 dissociations, involve
complex species "Receptor".
You may also select a complex species by clicking the item
"Receptor" in the tree panel.

Move nodes to adjust layout
Drag the complex species node "Receptor" in the
network panel to adjust the layout. You can move all nodes, both
complex species and intermediate nodes, in the network.
Select a rule
Select the rule "receptor liagation" by clicking
the item "receptor liagation" in the rule panel. Expand
the list of association rules by clicking the
button in front of "Association"
if necessary. Edges are highlighted to show which complexes as well as
complex species participate in the reaction rule "receptor
liagation". You may also select the rule by clicking the
corresponding intermediate node or edges.
The complex species node changes to display the involved complex
after changing its molecule component state(s) and binding site
status. For example, the complex "Rec inactive" has an
"off" component state, and a status of "don't
care" and "unbound" for the first and second
binding site. The second line of the text label shows the name of the
complex in blue (e.g. the complex "Rec inactive" of
the complex species "Receptor").

Show reaction rate of a rule
Hover over the intermediate node "receptor
liagation" or one of its incident edges to show the rate through a
tooltip "1e+07 liter/(mol*s)".

Select a complex
Click the item "Rec inactive" under the list of
complex species "Receptor" in the tree panel. Expand the
list first by clicking the
button in front of "Receptor" if
necessary. Edges are highlighted to show which reaction rules involve
the complex "Rec inactive". In this example, two reaction
rules, namely "receptor ligation" and "Ligand
dissociation", involve the complex "Rec
inactive".

Filter the complex species and complexes by name
Expand the filter panel. Select the radio button "By
name". Put in the text field "receptor" and click
the "Apply" button. The complex species and complexes
that contain "receptor" in their names are marked in yellow in tree
panel.

Put in the text field "gdp" and click the
"Apply" button. The complex species
"LigRec_Gabg" is marked in blue in the tree panel, indicating
that the complex species "LigRec_Gabg" does not
match the filter term "gdp" but at least one of its child
complexes matches the filter term. If necessary, expand the complex
list by clicking the
button in front of the item
"LigRec_Gabg" to find the complex
"LigRec_Gabg_GDP" marked in yellow.

Click the "Clear" button to clear filtering.
Filtering is case insensitive.
The user may use regular expressions to create compound filters.
Filter the complex species and complexes with regard to the constituting molecule
Select the radio button "By molecule". Select the
molecule "Ligand" from the list and click the
"Apply" button. All the complex species and complexes
that contain the molecule "Ligand" are marked in yellow.
Click the "Clear" button to clear filtering.

Find matching complexes with a set of complex-specific attributes
Complex-specific attributes are the molecule component state(s) and binding site status. You may specify a set of attributes and find matching complexes within the same complex species.
Right-click the complex species node "Receptor" and
select "Find complexes of 'Receptor'" in the context
menu. Starting from a set of molecule component state(s)/binding site
status where all states are set to "don't care", click
the icons of molecule component states/binding site status to change
their states.
A search state "don't care"
matches all possible states.
Change the molecule component state of "Receptor"
from "don't care" to "off" to see that the
complexes, "Rec inactive", "Receptor_2", and
"Rec inactive unbound" match the set of states and are
highlighted in tree view. The edges are highlighted to show which
reaction rules involve the matching complexes.
