[Chimera-users] Defining a zone around a point defined by x, y, z coordinates

[Jean-Didier Marechal]

Dear all,

We are having difficulties in defining a certain type of selection zones
in chimera. Our  problem is that we don't want to centre the zone on an
atom selection but on one point of the space defined by its 3D
coordinates. Typically we want to give chimera the x,y,z coordinates and
select all the atoms included in a sphere of 25 angstroms around this
point.

How can we do so?

Thanks a lot

JD
