Dear Bob,
Sorry for the delay in answering. I was very busy with Unviersity
activities and when i tried to post this message from my iPad it was
sent from the cloud.me <http://cloud.me> account and was refused from
the list manager system.
Jmol is working at its best! I had a look but I did not have time yet
to inform you about it.
Due to the new functionality It is now possible to ask a student how
many chiral carbons he can individuate into a molecule and probably this
could be done also leaving the student to make a selection on the
molecule and compare the result obtained using the selection piece of
script you showed in the examples. Also, this feature eliminate the
problem I had, to make exercises on molecules having only one chiral
sterocenter. Now, every chiral stereocenter can be individuated and
properly managed.
For people teaching Organic Chemistry this is an enormous advance. I
could imagine that by using the selection functions you implemented time
ago, for a biochemist it could be easy to individuate an unnatural amino
acid or sugar (for which the difference is only the stereochemistry) in
a complex biopolymer.
You did it on my birthday, so I would take this great advance as a
"present" that I can share with everyone, student or teacher, who is
interested in chemistry. Many thanks also for this.
I will introduce some notes on my site to explain that the new page
should be taken with care because it is "under testing" and I will ask
everyone doing exercises to inform us about problems and accuracy problems.
@Pino (who wrote in the meantime...): I only made a request for info to
Bob... He worked hard, and JMol/JSMol made a "quantum leap"! JMol is
always a piece of "magic".
Many thanks again!
Bye!
Pierluigi

I've added a "show R/S" button at

It just runs

background labels yellow

I have that fixed in JavaScript but want to add a couple more

also get jsmol.zip here:
https://sourceforge.net/p/jsmol/code/HEAD/tree/trunk/dist/
<https://sourceforge.net/p/jsmol/code/HEAD/tree/trunk/dist/> and
it should be working at the St. Olaf site. For example:

Ogg: [Jmol-users] check R/S chirality with Jmol
*Download Jmol-14.12.0-binary.zip (69.3 MB)
<https://sourceforge.net/projects/jmol/files/latest/download?source=files>
*
*Jmol now allows checking of R/S chirality. For example:
*
load $(R)-glycidol
print {C1}.chirality
/R/
load $cholesterol
select on chirality != ""
label %[chirality]
/8 atoms selected/
Thanks to Pierluigi Quagliotto for the suggestion to
tackle this. It was a good challenge getting it right.
Please test!
Bob
