Not specifically, but you can try changing morph parameter options and values to see how they affect the intermediate conformations. I'd probably try changing the coreFraction and/or using "cartesian true" first, but it's not easy to predict what will help.
Trial and error!<br>

not move in the intermediate frames also. Do you know how to overcome this?<br>

> This boils down to a morph question. Omitting the complication of the movie, just look at the trajectory and the two input structures. Unless you moved the morph trajectory model separately after it was created, the position at the first frame of the morph
trajectory should be exactly the same as the position in the starting structure input to the morph calculation, and the position at the last frame of the morph trajectory should be exactly the same as the position in the ending structure input to the morph
calculation.<br>

conformational change.<br>
