[gmx-users] Atom index (13154) in position_restraints out of bounds

[Yun Shi]

Hi all,

I want to restrain the OW of a bound water molecule for the MD of a
protein in water. But the index of this OW is apparently out of range
and I know someone would suggest merging this water with my protein
(e.g. put them in the same .itp file) so as to make them "one
molecule" and thus the index would not be out of bounds.

But I wonder if there is any other way to circumvent this issue?

Thanks,
Yun
