[PyMOL] Nucleic acid selection

[Robert C. <co...@mr...>]

I have a double helix shown in blue and want to highlight certain bases in
yellow. I have tried the selection in a similar way to amino acids but that
doesn't seem to work...

select junk, TRF1_dna ,chain X, resi 7-9

The object TRF1_dna contains both strands of DNA. The chains are labelled X
and Y and the bases are numbered 1 to 19 on both strands.

Any ideas on how I can select a string of 3 bases would be greatly
appreciated,

Cheers,

Rob Court
