Re: [AMBER] no bonds formed between AA and non-standard residue

Dear All (and David),
I think tleap residues start with 0, but in the pdb/prmtop-rst7 it writes
first residue as 1.
Assuming this is correct, I changed residue numbers in the bond commands
given to tleap and then read the prmtop/rst7 files in parmed and asked it
to printbonds :420,482 and printbonds :421,482 (shown below).
The output doesn't contain very large bonds (but some are < 0.7A and thus
high E), I hope minimization can fix this. (tleap terminal output is given
at the end; there is still a warning about 4A bond, which doesn't seem to
be coming from non-standard CYS-HEM, but not sure what/where is this long
bond still hiding!).

So parmed shows that the bond are there, but *I still can't see them in vmd*.
But strangely, the terminal OXT atom is still present, do I need to
explicitly delete it? Should it not get deleted when I bond the residue to
another standard/non-standard ones?

I think the fact that terminal OXT and NH atoms for 420, 421 are still
there is a problem and needs fixing before regular MD (min, heat, equil)
jobs can be started.
Please suggest on these aspects and any other issue that I may have missed
out.
Thank you very much.
