Hi Steve, I'll ask the other Chimera developers about making independent mode rotation use the center of the whole model when it is undisplayed. Unfortunately that is a change in the C++ that would not be available for a while. I'll try making a rotation/translation undo button next week. I think it can be done all in Python and I could just email you the code. Tom

Yeah, a rotation/translation undo would be great! The miscentering problem isn't an issue for what I'm doing right now (at least not much of one, but a more generic way of setting the center would be nice. Perhaps using the origin you set for the volume data as a center for rotation. The manual translations seem to be independent of this value...

cheers...
