That may be telling. Also note that their methods are also questionable (even
getting terminology like "constraints" wrong, using PRODRG for the ligand -
yikes!) so tread carefully. I haven't looked at the papers closely so I will
not comment much further.
It is unfortunately commonplace when writing methods to simply say the
simulations were performed with GROMACS, but conveniently leave out lots of
technical details like additional scripts, external wrappers, programs, etc.
The MD engine may have been GROMACS, but it was either (1) modified in-house or
(2) called as part of some larger workflow using scripting and other utilities.
