Thanks for the lightning quick response. Much appreciated.

Another possibility is to use the "turn" command to turn the object
around an axis by a number of degrees that you specify, and then
determine the correct number of degrees by trial and error.

Hi Jaap,
Maybe the "matrixget" command would meet your needs; it writes out a  
transformation matrix, 3x3 rotation matrix + translation vector, for  
each model:

You can write it to a file or just to the Reply Log.  If to a file,  
you can later apply the transformation(s) by reading the file with the  
"matrixset" command (same man page as above).

I'm trying to figure out how I can obtain angles from chimera. I  

have a 3D object that I have to rotate in order to see certain  

features. I'd like to know those angles. Is there is a way to get  

this info?


Thanks in advance,


Jaap Brink
