[gmx-users] disulfide bonds

I'm trying to work on thrombin pdf file with 2 chains. The pdb code is 1PPB.pdb
The main problem is: When I use pdb2gmx it adds H atoms to Cys,
hence the disulfide bonds are no longer conected after energy minimization.
How can I avoid this addition of H atoms?
(I tried to make this bond after, but I didn't make it because one Cys
is in the long chain and the other one is in the short chain)
