Dear VMD experts,

I am using VMD 1.9.2 from 29.12.2014. I got following error using FFTK
plugin while trying
to save psf file with updated charges:

can't read "ParaToolExt::ChargeOpt::psfPath": no such variable
can't read "ParaToolExt::ChargeOpt::psfPath": no such variable
    while executing
$ParaToolExt::ChargeOpt::psfPath "top""
    (procedure "::ForceFieldToolKit::gui::coptWriteNewPSF" line 28)
    invoked from within
    invoked from within
".fftk_gui.hlf.nb.chargeopt.results.container2.psfNewWrite invoke "
    invoked from within
".fftk_gui.hlf.nb.chargeopt.results.container2.psfNewWrite instate {pressed
!disabled} { .fftk_gui.hlf.nb.chargeopt.results.container2.psfNewWrite
    (command bound to event)

I get this when I hit "Write" button in the Opt.Charges--->Results card.

Now, what is more I have some other issues, for instance I cannot see Open
or Set As Initial at this card.

Any help will be much appreciated.

Best wishes,

Dawid Grabarek
