Dear ChimeraX Team,

I am currently working on visualizing peptide/Protein complexes and I’m having some trouble maintaining specific residue labels while clearing others.

My Goal: I want to label:

Protein (Chain A) residues that are within 5.0Å of the Peptide (Chain C) residue 1.
The Peptide (Chain C) P1 residue itself.
I want to ensure residues P2–P9 remain unlabeled.

Below is the script I am currently using:

set bg white

graphics silhouettes t

lighting depthCue f

size #1 ballScale 0.20 stickRadius 0.2

select /A & (/C:1 :<5.0)

show sel

style sel ball

color byhet

view sel

label sel text "{0.label_one_letter_code}{0.number}"

label @@display residues bgColor white

label height 1.0

sel #1/C: 2-9

label delete

The issue I am encountering is that when I execute:

sel #1/C: 2-9

label delete

it deletes not only the labels for peptide residues P2–P9, but also the labels for the protein interface residues that were previously defined and labeled.

Question:

Should I be using a more specific selector in the label command itself to avoid using select and label delete sequentially?

Any advice on the cleanest syntax to achieve this would be greatly appreciated!

Best regards,

Arun
