I am using ChimeraX to save the .pdb file of chains in a protein. Here are my commands:

+) open 7oci

+) select #1/E

+ save /.../E.pdb model #1 selectedOnly true

Then I opened that E.pdb model in ChimeraX and saw that chain E only contains helices. However, when I checked the .pdb file of chain E in a text editor, I saw that it contains sheets as well. The number of sheets are even larger (Number of helices: 52, sheets: 76). Do you know the reason why I don't see the sheets of chain E in ChimeraX? Am I missing something?

I have attached the screenshots and the pdb of chain E. I took this chain from the pdb ID 7oci.

Thank you very much. I am looking forward to hearing from you.

Best regards,

Thu
