Elaine,<br><br>Sorry for repeating the post. The previous post says that i can get the centroid by typing the following commands.<br>I opened a pdb file (attached) in Chimera. I typed sel, reset, focus sel. Then i got the centroid as <b>28,31,31</b>. I closed the session and opened the molecule again and gave Actions --> Atombs/Bonds --> show to display all the atoms. Then i typed the same commands sel --> reset ---> focus sel. the calculated centroid was <b>31.3,30.9,30.8</b>. Why am i getting a slightly different centroid in this case ?<br>

Hi Bala,<br>
You asked the same question earlier this year! Here is the answer:<br>

Friends,<br>
Is is possible to find the central x,y,z coordinates of a pdb file in chimera.<br>
