Hi Jeff, I added a user interface dialog for rotating and translating atom coordinates. Markers in Chimera are equivalent to atoms so it works on those. The rotation is specified in Euler angles. The new dialog, called Transform Molecule Coordinates, is available on the experimental features web page: http://www.cgl.ucsf.edu/chimera/experimental/experimental.html Tom Jeff wrote:

thanks Tom,

much appreciated. how hard is it for me to write a dialog GUI to provide 3 numerical inputs to the rotation script you forwarded me? (is it more involved than a few lines? I am not familiar with Tkinter).

don't want to bother you too much, if it is not a quick thing/response feel free to punt, please.
