Hi Elaine, Thanks a lot!

From looking at the release notes (Command Changes section), I see that "vop threshold" was added in Chimera 1.8. So you need to get Chimera 1.8 or newer! <http://www.rbvi.ucsf.edu/chimera/docs/relnotes/1.8.html> <http://www.rbvi.ucsf.edu/chimera/download.html> If you want the documentation to match what you have downloaded, use the Chimera Help menu. If you are looking at documentation online, it might not match what you have. Best, Elaine ---------- Elaine C.

Hi Elaine, I try to set values below certain level to 0 in a EM density map (mrc format) using vop threshold:
vop threshold #0 min 0.00007 set 0
But I got an error message:
Unknown vop operation: threshold

Could you please help me out? Thank you very much! Zongli
