PGRAPH: Software for Kinship and Marriage Networks (history)

see: Tool Kit for the Structural Analysis of Genealogical and Marriage Data

Doug White and Pat Skyhorse have developed this FTP/WWW site and completed the user's manual for Doug White's PGRAPH (c) 1997 research programs for kinship network analysis. The pgraph is a concept for a novel representation of such networks where the vertices are not individuals but intersections between individuals (as in marriage) or between groups and individuals, where graph-theoretic cycles and blocks are relevant units of analysis. Thanks to advances in computational graphics, the p-graph research community is no longer dependent on the p-graph package as the only means of rendering these graphs. The simplest pgraph option is to download the Ego2Cpl utility program, the Ego2Cpl manual and the 2002 Ego2all multiple format converter, (to Pajek, Pgraph, GEDCOM, and Raymond Barry's software - source code), or PG2Pajek dataformat converter, and then download Pajek and run it on the *.net or *.ged files it produces, depending on whether you want p-graph or conventional ego-network graphics. Or you can download the self-extracting installation files for a PGRAPH Version 2.6 for DOS on Win3.1
, a PGRAPH Version 2.6 for DOS that will run on Win95
, a PGRAPH Version 2.6 for DOS that will run on WinNT and Win2000
or another PGRAPH7 Version 2.7 for Windows, as well as updates for those who have downloaded earlier versions. The WINDOWS version 2.7 follows the formats of the Version 2.6 Manual for the DOS, but is free of three known bugs in DOS version 2.6. PGraph programs and their accompanying analytic and utility programs are called "The Parente Suite." The Parente Suite User's Guide, Vol. 1, containing a tutorial "Six Steps for Kinship Graphs: from Genealogical Data to Network Analysis," available here and in Rich Text Format (.rtf) and (*.doc) formats.

PGRAPHW for Windows is a BETA testing version with new white-background screen formats but comes with the warning that some advanced options of the 2.6 DOS and 2.7 Windows version are not yet available

Parente Suite Programs

• Ego2Cpl.exe transforms rectangular data files (individual number, sex, name, spouse #, fa #, mo #, birthdate, marriage date, death date, and other variables or text information) into PGRAPH files which have implicit numbering of couples (multiple rectangular data entries for individuals identify multiple marriages)
• PGRAPH.exe or PGRAPH7.exe build and help you analyze and edit network graphics where couples are points and individuals are lines connecting the points.
• The new Parente Suite User's Guide, Vol. 1,, contains a Tutorial edited by Skyhorse and Douglas White's section on statistical analysis of marriage and kinship networks, and how to produce publication-quality labeled p-graphs.
• Par-Calc.exe with sortf.com produces a statististical analysis of marriage structure and frequencies of different consanguineal marriages in the population
• A NEW Par-Calc.exe for later DOS versions of WINDOWS along with sortf.com is available to produce a statististical analysis of marriage structure and frequencies of different consanguineal marriages in the population
• Par-Link.exe lists pairs of marriages that relink pairs of families and links to a new set of programs (contact the author) for statistical analysis of relinking

  GRAPHICS PRINTING OPTIONS

• Par-hgl.bas and Par-plo.bas generate HPGL language instructions for printing vertor graphics output from the slides created by PGRAPH
• As an alternative way of getting printable raster or pixel graphics, BETA Windows version PGRAPHW.exe implements the main options of PGRAPH7 with graphics screens that can be transferred via the PrintScreen key into NotePad and Pasted into other applications such as Word, PaintShop Pro, etc.
• We are currently exploring other combined vector and raster graphics data formats for use with interactive web site displays of kinship networks. Format and software suggestions are welcomed.
