Thank you for the testing. I made an update. I will leave it here for a few days fro download so anyone is welcome to participate and give feedback.
The manual extract should have been solved now. The script accepts gzipped and text DUF's alike. I also solved a few other issues.

Of course we look at pose transfers from another figure and hand and feet will never be an exact match. Tweaks will always be necessary, even if the posed figure is a derivative of the original. 

I also made a simple hair morph donor for 2-click hair conversion and ran EZSkin on the figure.
