Selections are enclosed in parentheses and contain predicates, logical operations, object names, selection names and nested parenthesis: ( [... [(...) ... ]] )<br />

== USER COMMENTS ==<br />
Working efficiently in PyMOL --- or any molecular visualization program --- requires in-depth knowledge of selections & representations. You can select objects by more than just their residue name, number, etc; for example<br />
<source lang="python"><br />
# color blue, whatever is visible<br />
color blue, visible<br />
<br />
# show sticks, for all residues that have a b-factor of 2.0<br />
show sticks, all and b=2.0<br />
<br />
# show the surface representation for all residues within <br />
# 5 angstroms of any hetero atoms in all molecules<br />
show surface, byres all within 5 of het<br />
