Restraints don't prevent movement, only disfavor it. Have you quantified
this in any way? RMSD? Is there a "Position Rest." energy term written
to your log file? If so, the restraints are there and acting, but maybe
you need a different force constant.

I forgot the D in -DPOSRES in the previous email. However I used the
"define = -DFLEXIBLE -DPOSRES" but it doesn't work and position restraint
was not applied on the atoms. Is there another way to solve the problem?

Dear Gromacs Users,
If I wanna use some flexible bonds and also use position restraint on
some other atoms, how should I do this? the error arises because 2 define =
-DFLEXIBLE and -POSRES is not allowed in the .mdp files.
