Super simple question: did you load a psf file? That is what the error message is asking for.

Hi all,
I am parameterizing an acrylic acid molecule using the VMD fftk plugin. During dihedral optimization "scan torsions" window, when I load the gaussian log files, the following error is produced.

    (command bound to event)
I have followed all the procedures correctly for didhedral optimization and is unable to guess what might have been wrong. Kindly help.

Thanking You
