Hi,
I want to select only the protein backbone and the nucleic backbone and not
within 12 or resname X.
For that reason I type "proteinback or nucleicback and not within 12 of resname
X"
but the final selection included all proteins and backbone. Why?
I would appreciate if anyone could help me.
Thank you in advance.
