Hi,

I performed a dynamics for a unit cell containing a cluster of molecules using namd and I load a dcd file together with the corresponding psf one.

Along the dynamics, for particular frames, some atoms of the cluster move away from the unit cell. Thus, if I want to save coordinates into a pdb file for every frame, for these "wrong" frames, the pdb coordinates will be wrong (some atoms are far away from each other).
I only can rebuild the correct cluster using pbc wrap for one frame

How can I manage the dcd file (pbc wrap/unwrap ?) to tackle this problem ?

Best regards

Laurent
