Using target=_blank is strongly recommended because it opens a new window or tab (depending on the browser
and its configuration) for
FirstGlance, leaving the page containing the link(s) to
available behind the new window.
Replace the PDB identification code, in the above example, with the
entire URL to the desired PDB file. For example, under Toxins
in the Atlas
of Macromolecules you can find a model for the heptamer of anthrax
protective antigen, available from
This URL can be specified after ?mol= in the link to FirstGlance, but
colon (:) must be "escaped" to %3A. Thus, the link
If you are located outside the USA, and you get consistently faster
display of the molecule from a
FirstGlance Mirror Site,
you can use the mirror URL for your links by replacing
"firstglance.jmol.org" (in the examples above) by your preferred mirror URL.
By default, FirstGlance uses JSmol, which does not require
Java. For large molecules or smoother rotation, use Java
by adding this query parameter to the URL:
The Jmol Java applet is requested with &JAVA (or &SIGNED).
Do not use &JAVA in a link since the most popular browsers do not support Java.
Advanced options (available from the main page with the
Advanced Options link) can be specified in hyperlinks.
These options should generally be unnecessary. If you think you need
one of these options, please contact
to discuss whether it is, indeed, necessary.
Debugging mode is turned on with &db=1&
mmCIF format atomic coordinate files are requested with &cif=1&
(FirstGlance has not yet been adapted to work with cif files).
For example, to invoke FirstGlance
using JSmol (no Java), regardless of any preference setting,
in debugging mode, the hyperlink would be:
For test purposes, FirstGlance can be told to behave as if a specified browser were in use,
regardless of the actual browser employed. This is done with a "&spoof=browsername" query parameter,
where browsername is one of chrome, edge, ie, firefox, opera, safari, or maxthon.
These query parameters do not cause the browser to behave like a different browser --
they affect only FirstGlance.
Links that use these query parameters to display 1d66 are provided in the Updated section
for version 2.4 in
