[Chimera-users] How to change water molecule from triangle stick to folded line stick?

Hello, Hyeona!
Water molecules are sometimes defined with the extra H-H bond, to help them hold their shape during simulations.  

However, in Chimera you can just hide those bonds, for example with command:

bonddisplay off :wat&H

(show command line using menu: Favorites... Command Line)

You could also delete them, although you might not want to do that if you might do energy calculations later or save the file for energy calculations in some other program.  If you are sure you won't need the bonds later, you could delete them with command:

~bond :wat&H

Whether or not the bond is shown, you can still use any display style for the molecules: stick, ball&stick, sphere ...

I hope this helps,
Elaine
