Downloading Ego2Cpl (to download use Shift-Left-Mouse-Button) gives you access to a powerful tool for converting genealogical data into formats for network (NET) or genealogical exchange data (GED) files that can be used with Pajek, the package for large data analysis (see toolkit). Extensive error checking insures that your file does not contain contradictory data such as two mothers for the same person, two people who are each parents of one another, persons listed in one place as male and another as female and so forth; checking is also done for consistency between listing parents and appearance of those parents as egos in the same file. This format is ideal for taking data out of flat databases such as census listings, or copying data off printed genealogical charts through a numbering system. The alternative is to use genealogical input software available commercially or as freeware, and save the data as a GED file (extension *.ged) that can be read directly by Pajek.

The Ego2Cpl program, written by Doug White:
Assigns numbers to families
Checks and lists inconsistencies in the data
Creates a standard NET file for Pajek with P-Graph format:

Individual Names or Numbers are associated with Lines
and precisely what portion of the names you want to appear on the graph
Couples Names or Numbers are associated with Points
The network consists of parent/child links between families of origin and families of procreation

Creates a standard GEDCOM file for Pajek or Genealogical Programs
Where individuals are multiply married:

They are given a common family of origin
Men's lines are colored blue rather than black for men married once or single
Women lines are colored orange rather than red for women married once or single
