Summary: echo atom numbers
Initial Comment:
At the moment there is no way to determine the atom number of an
atom in Jmol, aside from reading it in the pdb file. IT would be
great if this info echoed to the console, through the pickCallBack in
the applet, and was shown in the 'hover' data.
thanks!!

atom number is now reported as part of hover, default label,
and atom click info

Chime and RasMol report the value of the atom number column in the pdb
file when an atom is clicked. this is useful (almost necessary) for setting
monitor lines between atoms in a script file:
monitor 134 1677
it is also useful for dynamic actions based on the pick event in the Jmol
applet - for example, color a picked atom, add a picked atom to the
selected set, etc.
function colorPicked(atomnum)
{
#atomnum comes from the pickcallback
document.jmol.script('select atomno='+atomnum+';color goldenrod;');
}
regards,
tim

I am not sure what you are trying to do ... I need a simple
example.
This is complicated but ... the third parameter to the
PickCallback is *not* the atom number. Rather, it is the
atom *index*. Atom numbers are something specific to .pdb
files. The atom index is used internally by Jmol.
I am actually quite reluctant to use this atom index. It
will be a source of confusion until we get a well-defined
API in place.

The third parameter in the callback is the atom number, but
I, ah, ECHO your request to generalize the pick callback 2nd
paramter to be based on the label %character format. The
command we are looking for is something like
pickcallback "This is atom %i with coordinates %x %y %z"
Right now the 3rd parameter to the callback function is the
atom index, starting with 0 for atom 1. (Same issue as frame
callback giving "0" for frame 1. Is this something that
should get fixed?) So if that is all you want, you have it.
But I do note that with 1blu this callback is NOT the number
in the third pdb column, because (a) it starts with 0, not
1, and (b) there is a "TER" record that is numbered but has
no atoms, so by the time you get to 614 the numbers reported
are the rasmol "serial number--may have gaps" (%i) minus 2.
The command "label %i" on the other hand, (as well as select
atomno=n) reports the "gapped" PDB number. So, for example,
in 1blu there is no "atomno=613" and no label with a 613 on
it using
select atomno>600 and atomno<620
label %i
select atomno=613
reports "0 atoms selected"
but picking atomno=615 reports to the pickCallback "613" in
that third parameter.
