Elaine, Sorry for repeating the post. The previous post says that i can get the centroid by typing the following commands. I opened a pdb file (attached) in Chimera. I typed sel, reset, focus sel. Then i got the centroid as *28,31,31*. 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 *31.3,30.9,30.8*. Why am i getting a slightly different centroid in this case ?

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