Jeremy,

G25 components for the Erfurt data here: https://anthrogenica.com/showthread.php?26176-The-Ashkenazi-founder-event-pre-dated-the-14th-century-(discussion)/page13  and here are K13s, which I believe can be used on Gedmatch: https://anthrogenica.com/showthread.php?26176-The-Ashkenazi-founder-event-pre-dated-the-14th-century-(discussion)/page17
(You may need to start a free account to access these pages)

I'm not sure whether anyone has uploaded the data to Gedmatch as a kit yet.
