I am new to Chimera and I have a question using the volume viewer:

I have three volumes (reconstructions from different tomographic reconstruction algorithms) to compare. They are in the same size and structure as saved in the .mrc files. I will rotate one volume and adjust the volume viewer and view it. And I then will create an animation video by adding 'roll' in timeline. But the question is, how can I make sure that when I open the other volumes, all of them are in the same starting position/placement, in order to compare and each frame in the animation video to make it possible to compare, because they should start at exactly the same volume position/placement. How can I set up this placement of the volumes to be the same?

Thanks very much in advance!

Best,
