Hi all,

I am Xiaobo Wan, a postdoc at UCSF. I would like to learn how to add chemical groups (such as methyl) or change chemical atoms (Fluorine to Nitrogen) using the command in Chimera because I have thousands of compounds to do the same modification. I know the Build Structure in the Graphic interface can do this. I am not sure whether the addgrp command was supported by chimera now.

Best,

Xiaobo
