To create a 3D p-graph
1. Click the left button
opposite Network, click your *.Net or *.GED file to open.
2. Click Net/Partition/Depth
to create a partition by generations.
3. Click Draw/Draw Partitions
and /Layers/Type of Layout/3D
4. Click Layers/in z direction
to add partition layers to the z dimension
5. Click Energy/Options/Starting
Position/Given Z
6. Click Energy 2D Fruchterman-Reingold/...wait/Continue
iterations
7. Click Spin/1 0 0/100
to rotate to a 3D representation.
OR: Click Options/ScrollBars
(they appear to upper left)
THEN: Click Options/Select
All, and use the ScrollBars to rotate in 3D
You can also spin in all
three directions by pressing or holding the keys X, Y, Z and rotating around
axis defined by the key S: spinning around as normally defined by (default
1 1 1).
When the part of picture
is selected (you select area with right mouse button), scrollbars are used
for travelling left/right or up/down.
To see only the largest connected
component
8. Click Net/Components/WEAK
(creates a new partition)
9. Click Operations/Extract
From Network/Partition
10. Click Net/PartitionS/Depth
11. Click Draw/Draw PartitionS
To create a 3D p-graph for
only the largest bi-component
1. Click the left button
opposite Network, click your *.Net or *.GED file to open.
2. Click Net/Components/BiComponents
(creates hierarchy)
3. DoubleClick Window 5
(Hierarchy) to bring up a new Window showing clusters
4. Click +Root in this new
Window to expand the complete list of bi-components.
Note the number of the one
with the largest size, for example.
5. Click Hierarchy/Extract
Cluster (and give the Cluster Number that you want to see)
6. Click Operations/Extract
From Network/Cluster
7. Click Draw (see Draw
operations above)
8. Click Net/Partitions/Depth
to create a partition by generations.
9. Click Draw/Draw Partitions
10. Click Layers/in z Direction
to fix generations in Z dimension
Or: Spin/Spin Around/1 0
0/90 to flatten layers to the Z dimension
and Then: Click Energy/Options/StartingPositions/Given

On Stopping and Restarting
2D Energy Iterations
1. As you run 2D Energy
iterations, you are asked to stop or continue every 20 sec.
2. You can stop, save the
Network, load it at a later time, and set Energy/Options/StartingPositions
to xy. It will resume where you left off.
On Export to Graphics formats
1. Click Export/EPS or PS
or VRML to create a graphics file to save your output.
2. The circles for vertices
in 3D get smaller in size as they recede, but this does not come through
unless you Export/WYSIWYG (Draw/Export/OptionsOnOff will cause options to
change if you change size of vertices).
VRML can be viewed on the web using the Cosmo Player plugin for
your browser or in viewers like HiJaakPro.
Note on using *.ged file input to Pajek: 5 output vectors are given for the dates of birth of the husband and the wife, their dates of death, and their date of marriage. Pajek reads the LAST FOUR DIGITS (or if only two, as in 1601/02, it ADDS 1900 and results in an error). Hence for date ranges write 1601 AND 1602 or BET 1601 AND 1605 for correct conversion of dates.
