[Chimera-users] on movie command

Dear All, Suppose there is a 100-residue protein opened in chimera, and it was scaled to a windows which can hold 10 residues, for example residue 10-20. Is any good way we first center on residue 15, then smoothly center on residue 16 (window hold residue 11-21), then smoothly center on residue 17 (window hold residue 12-22), then smoothly center on residue 18 (window hold residue 13-23), ......., until we center on residue 100? Here I emphasize "smoothly" so that the residue "move" was not too sudden to the eye. Best regards. Smith
