[Towhee-users] How to mention ntype and nunit

Dear all,
               I just started using towhee. I have pdb file for clay
structure, using the utility
I have generated towhee_coords file. In the towhee_input file, there are
some lines as shown below ,


unit ntype
   1 'at    '
vibration
 0
improper torsion
 0
unit ntype
   2 'at    '
vibration
 0
improper torsion
 0
unit ntype
   3 'at    '
vibration
 0
improper torsion
 0
unit ntype
   4 'at    '
vibration
 0
improper torsion
 0
unit ntype
   5 'at    '
vibration
 0
improper torsion
 0
unit ntype
   6 'Si    '
vibration
 0
improper torsion
 0
unit ntype
   7 'Si    '

My question is , do we need to manually edit this input file  and specify
ntype and nunit. or else is there any easier way to do this.

Thanks,
Mohan
