Dear all,
I am doing the molecule parameterization using ffTK tool, currently in
dihedral optimization step. In the opt.Torsional tab, I have loaded all the
requested files (LIG.psf, LIG.pdb and LIG_analogy.par and every scanned log
files). Now on Run optimization, I got an error stating " cannot write to
CWD ". I changed the directory to write accessible location from Tkconsole
and it works. But in between I end up in another error.

What is it all about? Any clue on this issue will do a great help to me.
