Dear all,

I would like to take a trajectory, calculate the coordinates of some
centers of mass in each frame and add these as dummy atoms into new PSF
and DCD files. These new files would then contain both the original
atoms and the new dummy atoms.

I looked into doing this with VMD but did not find a solution yet. Can
anyone give me an advice on whether this is possible whatsoever ?

Thanks

Best wishes
Vlad
