Selecting 5' oxygen returns an empty selection

[MattiMV]

I have a simple system where my dyes are placed on the 5' ends of my dsDNA construct. When I try and select the 5' oxygen for dye attachment I am returned the error:
"Position "D". Attachment atom could not be selected. Specified selection defines 0 atoms instead of one: 'chain D and resid 1 and resname DA and name O5' "
followed by
47:syntax error

Copying the above selection algebra and inputting it into pymol returns the correct atom, I tried messing with which symbol I use to represent prime ' or ′, neither seem to work.

I'm guessing this has something to do with the ' symbol being read incorrectly as any other ' marked atoms return the same error while all other atoms work as expected. I can bypass the issue by renaming the atom name to omit the ' symbol.

We are using Olga for nucleic acids. Hence, it is very unlikely that this issue is related to the atom naming. Note, Olga uses a VMD like syntax for defining selections. You cannot use a Pymol syntax. There are examples in the the repository.

If you still have issues, can you post a minimum example that reproduces your issues?

Pymol has no syntax for atom names, it's just the name value in the PDB file.
