[Pw_forum] Selective dynamics

[A Sen]

Dear all,
             Is it possible to do 'selective dynamics' with PWScf? If so, then how? By 'selective dynamics', I mean that certain atoms be allowed to move in certain directions while the others are kept fixed during structural relaxation of a semi-infinite system. 
I would greatly appreciate receiving your suggestions.
Best regards,
Arijit
