Hi All,
I am trying to parameterize a peridinin molecule to later run MD
simulations. Using paratool, I created a gaussian log file of the molecule's
optimized geometry. However, when I try to load this file into the base .pdb
file, it sends me the following error message:
can't use non-numeric string as operand of "-"
can't use non-numeric string as operand of "-"
while executing
"expr {[lindex $line 0]-1}"

(command bound to event)
I have tried this multiple times without any luck. Can anyone decipher this
error message and point me in the right direction?
Thanks,
Will Bricker
