Dear users,

I am using paratool for building topology/parameter for a fatty acid,
however when I am importing the guassian optimization output (log file) it
is giving error as :

vecscale: parameters must have data
vecscale: parameters must have data
    while executing

    (command bound to event)

Please help me to figure out the problem. Thanks in advance
