Download program for ΔG for TM insertion I am trying to calculate the ΔG of TM insertion for many protein sequences.

Has anyone come across the source code or a programmatic version for the von Heijne ΔG for TM insertion? The web server is at http://dgpred.cbr.su.se/index.php?p=instructions 

I can't find a link in the papers or on the site.
The application is stored in github (ElofssonLab/dgpred) with a link to the website. 

To find it I searched for: dgpred download github
