[求助] pdb2gmx出错

我在做一条肽链,但是它的一段由一个己基取代,也就是VAL里的一个氢原子去掉变成了一个己基,但是运行pdb2gmx时,提示
Fatal error:
Atom HN1 in residue VAL 1 was not found in rtp entry VAL with 10 atoms
while sorting atoms.

For a hydrogen, this can be a different protonation state, or it
might have had a different number in the PDB file and was rebuilt
(it might for instance have been H3, and we only expected H1 & H2).
Note that hydrogens might have been added to the entry for the N-terminus.
Remove this hydrogen or choose a different protonation state to solve it.
Option -ignh will ignore all hydrogens in the input.

我也知道是因为我用己基替换这个氢原子导致的,但是我又必须分析氢键,所以-ignh不会用到,请问我现在应该怎么操作阿?
