[PyMOL] Selection of elements in object

[Henrik G. <hen...@ch...>]

Dear Pymol users

Would anyone be able to help with the correct syntax used for selecting
specific elements within an object?

For example, I would like to be able to select only carbon or hydrogen.

select elem c (works but selects all the carbons in my project)
select elem c, obj (this selects all atoms within 'obj' as selection
'elem_c')

Any suggestions are much appreciated :)

Many thanks!
Henrik
