Preset range	corresponds to the drawings given in the Atlas of Zeolite Framework Types
User-defined range	initially this is just a little more than a unit cell; the range can then be specified in fractions of the cell parameters

to rotate around the   vertical axis	press left mouse button	move the mouse left / right
to rotate around the   horizontal axis	press left mouse button	move the mouse up / down
to rotate around the   axis ⊥ to screen	press Shift + left mouse button	move the mouse left /right
to zoom in / out	press Shift + left mouse button	move the mouse up /down
	use scroll wheel

The framework can be displayed with just the Si atoms or with both Si and O atoms shown. There are several different display styles to choose from: wireframe, stick, ball and stick, or ionic radii (1.4 Å for O atoms). Three stick widths are available.

Note: All models are idealized framework models in the highest possible symmetry

Four types of surfaces can be calculated and displayed (solid, transluscent, mesh or dots):

(1)	cages: defines closed cages, normally not accessible to sorbed molecules
(2)	channel system: defines the internal surface that is accessible to a sorbed molecule (see notes below)
(3)	two-sided channel system: different colors are used for the inner and outer sides of the channel surface. The two sided display works best for wider channels. The surface option radio buttons apply to the inner surface. Try using "mesh" with this option. To change the outer surface see Advanced Users below.
(4)	framework wrap: approximate "van der Waals" envelope of the framework. This surface is calculated around the oxygen atoms (radius 1.4 Å) by "rolling" a sphere with radius 1.4 Å around the framework.

For the channel systems there are three options for the surface resolution. The higher the resolution, the more detailed the features of the surfaces. After changing the resolution, you must clear the current surface (select "no surface") and then select the type of surface desired.

(i)	The calculation of the surfaces is done locally and can take time. The time depends on the size of the model and on the power of your computer - be patient. The status bar at the bottom of your browser will indicate if a calculation is in progress (script started) or finished (jmol script terminated).
(ii)	You can use the "hide all atoms and bonds" button to display just the channel surfaces and/or cages.
(iii)	When generating many different surfaces, the Java Applet might hang. Just reload the page. If this fails, restart the browser.

for surfaces: color $surfacename colorcode
where surfacename = cage or channel or outer or inner or wrap
Example
   to change the inner surface of the two sided channel display to "limegreen":
   color $inner limegreen

for atoms: select atomtype; color atoms colorcode
where atomtype = silicon or oxygen
Note: the bonds "inherit" the color of the atoms
Example
   to change the silicon atoms to "darkorange":
   select silicon; color atoms darkorange

for background: color background colorcode
Example
   to change to white background:
   color background white

colorcode:
The color can be specified in 3 different ways:
  - as a JavsScript color name (as in the example above)
  - in hex notation as [x32CD32}, see examples
  - in rbg notation as [50,205,50]
