Hi Thomas,
I think what you are looking for is fulfilled by the zoomto command.
zoomto (atomset) 0
will bring the atomset to (approximately) occupy the applet display.
I don't think this (the zero) is implemented for zoom, but I have not
tried it. Also, zoomto has a timing parameter, so if you wanted the
zoom to be instant, you could say
zoomto 0 (atomset) 0
-the first zero is the time in seconds that the zoom will occur over,
the second zero is the "fit the atomset to the display" setting.
See the documentation for zoomto for more options.

Hi All --
I've been mucking about with "zoom" today and wondered this: is it
expected behavior that the 100% level for zoom should be held
constant for a loaded model? What I mean is this: when a structure
is loaded, the 100% level is calculated by Jmol to be the factor at
which "all atoms are completely visible on the screen through all
rotations using the default vanderWaals rendering percentage." If I
then issue "zoom 200", the display is zoomed in by 200 percent --
expected behavior. If, however, I issue: "zoom (atom expression)
100" (for example, "zoom (*:B) 100"), would it not be reasonable to
expect the display to be altered such that the stated atom
expression is now scaled to (approximately) fit the Jmol display?
I'd like to use this to automatically transition to selected
portions of PDB files (such as ligands or amino acid ranges of
interest) and have the proper display zoom auto-calculated.
Is there another way to do this? Can I calculate on the fly a
boundbox for the current selection and set the zoom level to fill
the display with this new boundbox?
Cheers,
Tom
