[Chimera-users] Question regarding the chimera Transform Coordinates feature

Dear Ritwik Jain,
Not sure I understand your question, but I'm guessing you just want to save the atomic structure with transformed coordinates? If you move the atomic structure by any method (by hand with the mouse, commands like "move" and "turn" or fitting like "match" and "matchmaker") then you can save the transformed coordinates to a PDB file simply by using the "write" command. By default, it will write the transformed coordinates unless you also used the "relative" option.
If you have only one atomic model open, you can also do it by un-checking "Use untransformed coordinates" in the Save PDB dialog (e.g. opened from File menu).
I hope this helps,

That feature has an option to move atoms instead of coordinate axes (Img2.jpg). If I uncheck that box and transform, the model just reverts back to its original position after saving and reopening. I was wondering if there was a command line command for the " move atoms instead of coordinate axes " option. I have tried all the move commands (https://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/midas/move.html) and they don't seem to work.
