[Chimera-users] Very similar structures

Here's a crazy trick to see atoms in structure #1 that are not in
mcopy #0 #1 set v
This hides all the atoms of #0, displays all the atoms of #1, then
copies the visibility of atoms in #0 to matching atoms in #1. In other
words it undisplays just the atoms of #1 that have mates in #0.
You could abbreviate this command sequence
alias ^diff ~display $1 ; display $2 ; mcopy $1 $2 set v
diff #0 #1
diff #1 #0
Here is the mcopy documentation

In case your structures have consistent nomenclature, I have appended a script that will print the differences to the reply log and select the differences on the structures. You run the script simply by opening it with File->Open.
