Hi Damien, The Chimera 1.4 turn command can do a precise rotation for you. For example, turn -0.00376406,0.97263698,-0.23229967 0.5 model #0 coordinateSystem #1 Here is the manual page: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/turn.html Tom -------- Original Message -------- Subject: [Chimera-users] Apply rotation with precision From: Damien Larivière To: chimera-users Date: 11/12/09 9:48 AM
Dear Chimera team,
Once two pdb structures are opened, the command measure rot #1 #0 give the orientation of one structure with respect to the other one under the form of:
Position of 1Wxx_chB1.pdb (#0) relative to 1Wxx_chB1.pdb (#1) coordinates: Matrix rotation and translation 0.99727151 0.01713873 0.07180395 46.50921950 -0.01715871 0.99985272 -0.00033862 3.66357812 -0.07179918 -0.00089436 0.99741871 15.01300748 Axis -0.00376406 0.97263698 -0.23229967 Axis point 231.74603365 0.00000000 -638.91369622 Rotation angle (degrees) 4.23351417 Shift along axis -0.09924878
Let's suppose that I want to decrease the rotation angle from 4.233° to 0.5°: I can use "Movement" and select the model to be rotated in order to do that with the mouse but I will not be accurate. Is there way to do such rotation with precision?
Thank for your help
Damien
