Hi,
because of some problems and many features that have been changed in the newer version, My suggestion is to work with Ubuntu 16.04 LTS instead of 2018 version.
By the way, I have loaded these files a few minutes ago into fep plugin of VMD and easily plotted these values with xmgrace. I think your problem is related to loading file!
Please load <aqua-forward-on.fepout> & <aqua-backward-on.fepout>.
I hope to done.
Regards,
soroush
