You need to load a PSF and PDB at the top of the tab.

Hi FFTK/VMD Development Team,

I am trying to visualize one of the dihedral scans for ethanol (given in the tutorial).

I am doing the following:

1. Navigate to the "Scan Torsions" tab.
2. Use the "Load Dihedral Scan Log Files" at the bottom of the page to visualize the file "ETOH.scan1.neg.log".

I get the following error:

can't read "::ForceFieldToolKit::GenDihScan::psf": no such variable
can't read "::ForceFieldToolKit::GenDihScan::psf": no such variable
    while executing
"if { [llength $glogs] == 0 } {
                unset glogs
            } elseif { $::ForceFieldToolKit::GenDihScan::psf eq "" |..."
    invoked from within
".fftk_gui.hlf.nb.genDihScan.generate.load invoke "

    (command bound to event)

I am using VMD 1.9.4a12. Could you please advise me on how to resolve this?

Thank you.

Kind Regards,
