[求助] g romacs 计算氢键求助

我用GROMACS进行自由能计算，也想分析一下H键作用。但是由于我所要分析的肽链一端是用己酸修饰，我就用己酸基取代了氨基算个的一个氢原子，也就少了一个H，导致力场出现问题
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.

我想问下，如果我在这里使用-ignh的话，对后面的氢键分析会不会产生什么影响，谢谢大家...
