[gmx-users] doubt about constrain

[sudheer babu]

hi gmx users,
i have one doubt regarding constriants,i want to do production run of popc
in water. In my pr.mdp file i have used constraints of all-bonds,
but in case of production which type of constriants i have to use ? i have
checked gmx archives some people used "all-bonds" constraints, some people
used "none" contraints and some other people used "H-bonds" constraints in
md.mdp file of membranes.
which type of constraint i have to opt??
anyone help me pls
thanks in advance.
