Hi Miao, I can't figure out the issue unless you also provide the example PDB file... a picture is not enough information. If OK to share this data with others, you can send it to chimerax-users, or alternatively just to me. Without the file, I can only guess that maybe the atom and residue names are not the usual atom and residue names for peptides/proteins. Thanks, Elaine ----- Elaine C.

Dear Sir/Madam I have a small peptide that I want to show as cartoon. But chemira does not recognize it as a protein. I cannot show it as cartoon. I can only show it as surface, sphere, or sticks. How can I show cartoon? Many thanks Miao <image001.png>
