How to view the exhibits at The OMM
Assuming you are using >Netscape 3.0, have downloaded and installed
Chime (see Required software), and
have restarted Netscape, you should now be able to visualize the following
B-DNA molecule:
If you see a strange symbol, ,
instead of DNA, you do not yet have Chime working appropriately. Perhaps
you have installed a version of Chime intended for a different operating
system, or you have installed Chime in a different directory than the directory
your working version of Netscape is in? Try installing again, carefully
following instructions at the MDL
Chime site.
If you DO see DNA above, you are ready to visit the exhibits at the
OMM, but before you do, here are a few tips to enhance your visit.
As you explore a display for the first time, it is recommended that you
not manipulate the molecules on your own, but rather follow (i.e.
click on), in order, the built-in cue buttons that look like this: (note
the effect on the DNA, above). You can now easily distinguish the base
pairs and the ribose-phosphate backbone
of the molecule. In a given display, text describing a particular molecular
feature will be followed by a cue button that will elicit a relevant change
in the rendering of the molecule, similar to what you have just seen. If,
at any time, you wish to restore the molecule to its starting state, use
the reload button of Netscape to refresh the page.
You can also easily change the orientation or rendering of the molecules
on your own. Here is a table of mouse commands with indicated results (may
we suggest that you print a copy of this for later reference?):
Desired Result |
Windows |
Macintosh |
Activate Chime's menu |
Right button |
Click, (don't drag) |
Rotate X,Y |
Left button, drag |
Click, drag quickly |
Translate X,Y |
Ctrl-Right button, drag |
Command* click, drag |
Rotate Z |
Shift-Right button, drag |
Shift-Command* click, drag |
Zoom |
Shift-Left button, drag |
Shift click, drag |
Slab Plane |
Ctrl-Left button, drag |
Ctrl click, drag |
*On some Macs, the Option (Alt) key has the same effect as the
Command key.
For example, if you are using Windows, with
a cursor in the molecule frame (try it, above!), clicking the left mouse
button and dragging will rotate the molecule around the x and y axes. Clicking
the right mouse button will activate a menu which allows the following
manipulations:
-
Change the display type (renders the atoms in different ways)
-
Change the display options
-
Change the display color (colors atoms according to the cpk standard or
as members of a set)
-
Turn on and off molecule rotation
-
Store the input file (*.pdb) locally
-
Activate an "about" box
One final tip...explore the hot text in the tutorials: clicking
on it will either change the molecule, or lead to further information.
The Exhibits
Exhibits updated on November 16, 1998
The macromolecular displays at the OMM are grouped in "halls", according
to function, as follows:
Note: the atomic coordinate (PDB) files have been
gnu-zipped to speed downloads, but some files are still large (up to ~1Mb),
so please be patient...we've tried to make the tutorials worth the wait!
