[Chimera-users] How to make bonds between two pdb files

Chimera won't move the atoms when it creates the bond, it simply adds
the bond. So one issue is that the user needs to manually position
one structure relative to the other before adding the bond.
To move the structures separately with the mouse, you can toggle their
activation status, for example using the Active checkboxes in the
Model Panel (under Tools... Favorites).
The second issue is that you can't bond atoms in different models, so
after the desired relative position has been attained, combine them
using the new "combine" command
or "copy/combine" function in the Model Panel (you need a recent daily
build for these to be available).
Then the bond can be added with the command "bond"
or Build Structure (under Tools... Structure Editing), Add/Delete
I hope this helps,
