I atached my pdb files,beta1.pdb is the original file beta.pdb the one that I chang.
Yes it has the bond and I did change this pdb file so that RESI(0)+RESI(1) become RESI AHS
The missing bound is between RESI (AHS) AND RESI (LYS 2) and LYS(10)and (AHE).
I need to know how I let the topology file think that AHS and AHE is conected to the rest.
Thanks

Does your pdb have the bond before you run psfgen? And do you load
the psf and then load the pdb into VMD? Also, which bond is missing?
I expect any more information you could provide would be helpful in
this case.
