Dear Dr Gumbart,

Thank you for the response. I thought that the button "Load Dihedral
Scan LOG Files" on the "Scan Torsions" serves the same purpose as "Load
LOG Files" at "Water Int" tab, namely to verify whether the scans
calculated make sense and do not show any artifact. Having that failed,
I didn't expect that reading the same files at the last tab will
actually succeed.
I have just checked that at the last tab "Opt Torsions" the optimization
goes without errors so its only this mysterious button "Load Dihedral
Scan LOG Files" which does not work.

I'm CC-ing the VMD list in case someone having a similar problem.

Gretings,
Paweł Kędzierski

Normally, after generating the scan inputs and running them, we move on to the last tab, so we haven’t run into it in my lab.

I remember FFTK being picky about Gaussian version so I have tried with versions 2009 B.01, D.01 and E.01, and I believe Gaussian 2016 was not yet available a year ago, at least not in our supercomputing center :).
