HI all users,
I have tried a simple case with two atoms using [position_restraints] but
always it shows the same error :
Segmentation fault (core dumped)
But after I don't use the position_restraints for one atom and then I can run
the case smoothly. It seems that the gromacs doesn't recognize this
[position_restraints];
That may just indicate instability due to the restraints themselves; i.e.,
fixing atomic positions leads to a crash.
Then, I tried the freezegrps but it seems to restrict a whole group. Here, I
wonder whether I can just use this method to restrict several atoms in a whole
group and how to do that.
Like any other Gromacs tool, you can specify a custom index group as your group
to be frozen.

Thank you for your any suggestions.
