[chimerax-users] Unable to select individual glycans in ChimeraX

[Coillie, Julie van]

Dear ChimeraX,

Is there any way to select one individual glycan on a crystal structure?

The crystal structures I'm working with have multiple domains, each with glycans. I want to annotate the glycan per domain (every domain & glycan in a specific color). However, I can't edit individual glycan structures. The glycans are grouped under Non-standard residues, e.g. MAN, NAG, ... However, when selecting e.g. MAN, all the MAN structures light up, which are found on all 3 domains.
An alternative would be using the sequence and annotating each individual sugar by using "select". However, these Non-standard residues are not in the sequence (they are when uploading this in Pymol), so I don't know a position to select them on. Is there a way to find the "sequence" for non-standard residues or any other way to annotate an individual glycan.


Thank you in advance,
Julie Van Coillie
