<div>== DESCRIPTION ==<br />
[[pseudoatom]] adds a pseudoatom to a molecular object, and will create the molecular object if it does not yet exist.<br />
<br />
== USAGE ==<br />
<source lang="python"><br />
pseudoatom object [, selection [, name [, resn [, resi [, chain<br />
[, segi [, elem [, vdw [, hetatm [, b [, q [, color [, label<br />
[, pos [, state [, mode [, quiet ]]]]]]]]]]]]]]]]]<br />
</source><br />
You can set the following:<br />
[[select|selection]], [[name]], [[Property_Selectors|resn]], [[Property_Selectors|resi]], [[Property_Selectors|chain]], [[Property_Selectors|segi]], [[Property_Selectors|element]], [[Property_Selectors|vdw]], [[Property_Selectors|hetatm]], [[Property_Selectors|b-factor]], [[Property_Selectors|charge]], [[color]], [[label]], pos (location in space), [[state]], [[mode]], and quiet.<br />
<br />
== EXAMPLE ==<br />
<source lang="python"><br />
# create the pseudoatom<br />
pseudoatom tmpPoint, pos=[10, 10, 10]<br />
# show it as a sphere.<br />
show spheres, tmpPoint<br />
<br />
# create another, with more options.<br />
pseudoatom tmpPoint2, resi=40, chain=ZZ, b=40, color=tv_blue, pos=[-10, 0, 10]<br />
<br />
# working example<br />
load $TUT/1hpv.pdb<br />
pseudoatom tmp, pos=[10.0, 17.0, -3.0]<br />
show sticks, tmp expand 6<br />
delete tmp<br />
</source><br />

== NOTES ==<br />
[[pseudoatom]] can be used for a wide variety of random tasks where on must place an atom or a label in 3D space. <br />
