[AMBER] ptraj centering problem

Hi all,

I am trying to center all trajectory frames after simulation, as suggested in several tutorials and manual:

trajin protein_prod.mdcrd 1 150 1
trajout protein_prod_centered.mdcrd nobox

rms first out rmsd.out .CA,C,N

center :1-122 mass origin
image origin center familiar

strip :WAT

The rmsd looks fine, but when I run the MD movie application in Chimera with the re-centered coordinates file, the result looks horrible, the bonds of the protein are wrong and not all the frames are uploaded.

What am I doing wrong?

Thanks a lot in advance,

Fabian
