[chimerax-users] Superimposition of Carbohydrate Molecules

Dear ChimeraX, I am trying to superimpose multiple carbohydrate chains using chimeraX. Using match command, I am unable to do the same. Here is my command: *match #2:1-4 to #1:1-4* But I am getting the following error:

Reference and/or match model contains no nucleic or amino acid chains. Use the command-line 'match' command to superimpose small molecules/ligands.

Already I am using match command, still why the same error is showing?

Please advise me on how to proceed?

Thank you in advance.
