Bob,
I realize that Jmol uses Ajax. So I’ve been using Ajax all along. This was my
first time I wrote the Ajax HTML and JavaScript myself to communicate with
server-side PHP code I also wrote myself. So it felt different to me.

InChI is very messy because there’s more than one version of the program that
generates it. So depending on what version you use, you get a different InChI.
That information about which version of the InChI rules you are using is an
early part of the string. The other problem with InChI is that the strings can
be REALLY LONG, as in so long that it’s not possible to use them when you
search Google. That was another take-away from the course.
You do have to define the rules so that you get the sections right. Beyond
that, I suppose it may be true, but not for simple molecules. Any changes by
version would be for esoteric species (I am guessing.) What you are saying
violates the whole premise of InChI. Do you have examples, Jennifer?
2. Quick Facts
2.1. What is an InChI?
InChI is an acronym for IUPAC International Chemical Identifier. It is a string
of characters capable of uniquely representing a chemical substance and serving
as its unique digital ‘signature’. It is derived solely from a structural
representation of that substance in a way designed to be independent of the way
that the structure was drawn. A single compound will always produce the same
identifier.

You are using AJAX every time you use JSmol. All files are transmitted using
AJAX, and within JSmol you can do AJAX as simply as
x = load("http://......";)
I don't see why you would need any server-side piece these days. It is
certainly not "elegant" in my opinion. Elegant is
if ("my SMILES string".find("your SMILES string", "SMILES")) prompt "You're
good to go!"
without any concern for where the strings come from. That's what JSmol does. No
server required. Just make sure you are using the right options in JSME. See
http://chemapps.stolaf.edu/jmol/jsmol/jsmetest2.htm
}
var JMEInfo = {
use: "HTML5"
,visible: true
,divId: "jmediv"
,options : "autoez;nocanonize"
}
Here's a note I have on that from an earlier jmol-users post:
JSME and 2D/3D - It turns out that JSME has two modes of delivery of SMILES --
"canonize" and "nocanonize"...The problem is that "canonize" delivers aromatic
symbols for rings that are not huekel-aromatic -- all six carbons, for
example, in benzoquinone. Jmol does this, too, but Jmol adds double bond
indications as well, so ...c=cc=c.... The difference is significant -- Jmol's
SMILES representations are interpretable by the NCI Resolver; JSME's "canonize"
versions are not. So I have to have JSME in nocanonize mode in order to
convert 2D to 3D using the NCI Resolver.
