iTasser - how to define "restraint" parameters i.e. use of a specific PDB template for modelling?

Hello,

We are attempting to use a specific PDB for the threading/modelling.

In the optional arguments it appears that one is able to use "-restaint1/2/3/4", however when run with this argument it is not taking it but instead utilizing the other arguments (i.e. homoflag, idcut, ntemp etc.)

Could anyone please advise how to use the "restraint" argument.

Thank you kindly,
JN
