[PyMOL] How to label on surface

[sunyeping <sun...@al...>]

Dear Pymol users,

I wish to label the one-letter residue names for a bunch of selected resides on surface representation of a protein, but I found the labels cannot be seen on the image. It seems that these labels can been seen on cartoon representation when the surface is hide.
Could you tell to how to show the labels on the surface?
I will appreciate any help!

Best regards
