Hi Francesco, I'm not sure I understand what you are asking. Maybe you are saying that when you hide a model, the centroid is also hidden? Instead of hiding the model with the Model Panel "Shown" checkbox or command "~modeldisplay", which hides everything in the model, you can undisplay the protein parts and leave the centroid displayed. For example, if I had protein models #0 and #1 and also centroids for each of those, I could undisplay the protein part only of #0: ~display #0 ~ribbon #0 ~surf #0 (commands to undisplay atoms/bonds, ribbon, and molecular surface of model #0). Then, you would have the protein #1 plus the centroids of both #0 and #1 displayed. I hope this helps, Elaine ---------- Elaine C.

Actually, it is the same model, differing, in the movies, for the protein fluctuations.
What I did, was to superimpose movie for model 1 to the already done movie for model 0, hiding the protein for model 1 and choosing a different color for the centroid. Doing that, the instant position of the centroid can only be color-highlighted for model 0.
I wonder whether there is a better procedure to show the various centroid traces above a single protein model. thanks francesco pietra
