Dear OpenMx users,

For those interested in DF analysis, we have written a script which
in part 1 prepares / transforms data as in Purcell's means.gawk and prepare.gawk scripts
and in part 2 runs DF-extremes analysis.

Ref: Maximum likelihood DF-extremes analysis based on Purcell S. & Sham PC, Behav Genet. 2003 May;33(3):271-8.
"A model-fitting implementation of the DeFries-Fulker model for selected twin data".

Please let us know if you have any problems or questions.
