Dear Petro,

Text labels in PyMOL ( are displayed per atom, so the usual way is to make a pseudoatom ( for each helix label you want to make.

Using selections this can be pretty straight forward.

Let's say you have your coloured helices as selections you could do something like:

zoom helix1
pseudoatom labelhelix1
label labelhelix1, "Helix 1"

The position of the label can be changes using the edit mode  (see e.g.

Hope this helps

Best regards,
Folmer Fredslund
