[Chimera-users] center of molecule

[Bala subramanian]

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 ?
