# [Chimera-users] moving to coordinates

```Hi Conrad,

first you have to convert the mentioned angles to degree. They are
represented as rad here. (first 3 values in the translation file)
The formula for this would be rad*180/pi. We don't know why, but for the y
angle you have to switch the algebraic sign. Simply multiplied by -1.
We just did the conversions in Excel.

The rotation in PatchDock is in XYZ notation, first rotation, than
translation (this would be the order you also have to use by appling the
coordinates)
Then we just loaded the receptor as well as the ligand, apply the changes
you want (e.g. color active sites etc.) save it into a session file and
wrote a little chimera command file containing the following:

close session
open Z:\Sebastian\2013\Liganden\ohne Liganden\PatchDock\2+3\reference.py
cofr 0.0,0.0,0.0
cofr fixed
turn x -28.32 models 1
turn y  -42.12 models 1
turn z 128.78 models 1
move x 33.96 models 1
move y  68.95   models 1
move z   212.57 models 1

now you can just edit the turn and move values, open the command file and
Chimera will perform the orientation.
