[Mahboobeh Eslami]

hi dear Justin
 
You've written the following context in your tutorial:
 
 
Force field (GROMOS96.1/GROMOS87): "GROMOS96.1" refers to the first version of the GROMOS96 force field, 43A1.  "GROMOS87" refers to the (outdated!) GROMOS87 force field.  Choose "GROMOS96.1" to get 43A1 parameters for our ligand
 
but I don't see the option for Select the force field in PRODRG server
please guide me
thanks
sincerely
