dear all

I am using VMD version 1.9.2a33 (Aug 19, 2013) LINUXAMD64 for
parametrization of a new

I obtained the partial charges and started the process of optimizing bonded
parameters based on the Hessian log file generated using Gaussian 09, Rev

Hessian log file successfully generated, thanks to Gumbart (suggestion for
modifying the input for Rev C.01)

I used psf/pdb , hessian-log and input parameter file in the process of
optimizing bonded parameters

However after few seconds of the process, it exits with the Error: missing

please find here the complete error message below

missing close-bracket

This seems to be connected with the Tcl script.

I hope some of you might have optimized bonded parameters for some new
molecule with fftk, could you please let me know if this is an issue with
1.9.2a33 ?

or am i missing some thing here

thank you
best regards
