[Chimera-users] Difference between atoms' coordinates on screen and in a PDB file

Maybe I'm not understanding the question. You could make a Chimera command file (just a text file, filename ending in .com or .cmd) that has the move commands in it. You could first open the original structures and then open the Chimera command file, which would execute the commands. If you are making an animation with a script, those commands could be at the beginning of the script before the recording. My only other idea is to just save a Chimera session, which can later be restored.

The software generates a text "history" file with a list of all the moves the components make and a PDB file which is a result of those transformations. After applying all the transformations listed in the history file using Chimera, the stuff that's displayed on screen does not match the "result" model from this other software. Hovewer, if I save the result of my Chimera transformations into a PDB file, it perfectly matches the result file from the other software.

The structures are not overlapping (screenshot: http://i.imgur.com/gtGBN.png ). Why does it work like this and what can I do to obtain accurate coordinates on my screen without re-opening the model (after I finish my sequence of translations)?
