Title: Sandbox?
Post by: curiouscat on December 01, 2012, 08:39:17 AM
Can I request a Sandbox thread or area? Often I can't get my LaTex code or SMILE right at first go and it'd be nice to have somewhere to test. I sweat trying to compete against the 30 minute modify limit.   :)

PS. The Preview feature doesn't seem to render Tex? Or maybe it's only my stupid browser?

Wondering what others think..
Title: Re: Sandbox?
Post by: Borek on December 01, 2012, 08:55:16 AM
Tex is not rendered in the preview and unfortunately there is not much that can be done about it - preview is fetched from the server without reloading the page, and MathJax script runs on a page load. On the other hand SMILES images are created server side, so they are displayed in the preview.

We can devote some thread to testing and delete the content now and then, no problem. I can't think of a better solution at the moment. But I am open to suggestions.

It is possible to create some simple sandbox for MathJax, but it would be not integrated with the forum itself, not the idea that I like.

Just had a thought, can you PM yourself to test it?

New lines should be dealt with (almost) correctly now.

ALT text is still wrong, but this is more difficult to deal with due to the way things are organized in the forum code.

Not always good for forum formatting, but apparently the engine survived.

Although rendered image is not following IUPAC suggestions - it should be more compact. There are things that can be improved in the indigo, so far one of my suggestions made its way into the code (but I have no idea when it is will be released).

Was trying to throw Fullerenes at SMILES for fun but can't seem to make it work.  Any ideas?

Buckministerfullerene

Stealing the SMILES string off ChemSpider / Wikipedia:

c12c3c4c5c1c6c7c8c2c9c1c3c2c3c4c4c%10c5c5c6c6c7c7c%11c8c9c8c9c1c2c1c2c3c4c3c4c%10c5c5c6c6c7c7c%11c8c8c9c1c1c2c3c2c4c5c6c3c7c8c1c23

Incidently shouldn't the molecule have 60 C entities since it's a C60?  Was surprised that the Wikipedia / Chemspider strings only went up to C11. What gives?

Even the smaller Dodecahedrane  doesn't seem to work.

C12C3C4C5C1C6C7C2C8C3C9C4C1C5C6C2C7C8C9C12C31C%10C2C5C%11C6C8C(C1C9C4C7C(C2C34)C5C6C7C89)C%10%11

PS. As an aside Annulene looks pretty

C1=CC=CC=CC=CC=CC=CC=CC=CC=C1

Though this might have been a better way to render it (also as per Borek's very nice IUPAC guidelines):

You can PM yourself Tex to test it.

"You have exceeded the limit of 10 personal messages per hour."

Not a big deal at all, but just was funny how one can keep hitting the law of unintended consequences.  ;D

Who'd have thought of Dan's idea and then all because it took stupid me 10 attempts to get this SMILES right:

[*]C1OC1[*]

Was even funnier coz' Reply or Quote is the only way to get the SMILES in the past message sandbox attempts and SMF won't let me try that now. (Ha! If someone gets what I write! ).

Guess I'll be in the doghouse for an hour!  :P

PS. Is there a way to get R1 and R2 rendered in SMILES?

Another thing to report, once I am sure it is something to report  :-\

Turned out problems with C60 are somewhere on our side - I was unlucky enough to hit two separate bugs on the forum and on my own computer, I assumed if it doesn't work here nor there it must be a problem with the SMILES renderer - but that's not the case.

Did you have to do a lot of coding to integrate SMILES on "our side"? Wondering what "our side" bugs are like..

Something like several hours to modify forum sources - including time needed to find out how the BBC tags are analyzed and where. But it took several days to compile the renderer, as we discussed in the past.

And I have no idea what the bug is - yet. Most likely % sign is treated incorrectly. Trick is, I don't pass it - I have modified the program so that what is passed is just a hexadecimal representation of the original SMILES (so 434F is passed instead of CO), this way I don't have to care about the data sanitization (assuming the renderer just ignores incorrect input; I bet it does).

C(C)(C)[C@H]1CC[C@@H](C1)O and C(C)(C)[C@@H]1CC[C@H](C1)O

Not really, in this case there are a cis pair and a trans pair of diasteromers.

Your compound also includes C(C)(C)[C@H]1CC[C@H](C1)O and C(C)(C)[C@@H]1CC[C@@H](C1)O to my mind.

In a previous life I worked indirectly with DAYLIGHT on a few things, a sample presentation (not by me, but by someone who was in effect my boss) is at http://www.daylight.com/meetings/emug04/Lock/index.html

The cases we are discussing are ~ slide 20-23

I seem to recall that in the GSK system (as referenced above) there were "chiral" and "racemic" flags you could put on the molecule when imported from ISIS draw (as was) which helped distinguish these cases. Not sure how it worked on the back-end though :(
Title: Re: Sandbox?

I would draw one enantiomer and indicate that it is racemic with a (±) symbol underneath it.
Title: Re: Sandbox?
Post by: Dan on February 20, 2013, 01:47:49 PM
Another incorrect "chiral" flag today -but more obviously incorrect. It seems as though specifying configuration of even non-stereogenic centres fools it into assuming the molecule is chiral:

Both are OK with me - it really depends on what you are trying to show. The latter is simpler, but if for some reason you want to stress out you are talking about alkyne - teh latter makes sense.

In this particular case I would not use neither SILES nor LaTeX. Call it a personal preference.

(ac) comes from "acuoso", aqueous in Spanish. I used it all over my Olympiad exams, without any penalization, because the entire exam was in Spanish.

Those zinc equations were for an assignment. In Spanish again.

I was taught to use (ac), as you can see. This is what every future Olympic will be taught, so I'll try to show this discrepancy, and an example of what happens when they use (ac) instead of (aq). I'll use (aq) as long as I don't forget when posting here, also.

When I looked up the smiles for the Cobalt oxides WIKI was different than SPIDER
But they both had the same for the Glycerin (Glycerol)

Is there a source for "standard smiles" compounds?

SMILES are good for organic compounds, with well defined structure (bonds between atoms). Most inorganic compounds are more ionic and don't have easily separated molecules, so they may have well defined crystal structure (ie respective positions of atoms in the crystal) but no typical "bonds" yielding structure similar to the one in organic molecules.

IOW: SMILES are a good equivalent of stick and ball models, but not so good for infinite crystals.

Definitely a bug in the SMF engine, it ignores noparse (and nobbc) tags. I will see what can be done, but it requires digging in the SMF code.

I noticed in  the previous post that the link I posted leaves off the last parenthesis
which leads to an inaccurate link
so I am playing to see why

 https://en.wikipedia.org/wiki/Poly(methyl_methacrylate) (https://en.wikipedia.org/wiki/Poly(methyl_methacrylate))

I noticed I had to use the insert hyperlink function to get the required result

It seems that just a copy paste does not always work for links
I think I noticed this before but probably did not remember and I do not remember  why this is caused

Closing parenthesis is a known source of problems in links, especially in older software. Best approach is to use url tags.

CaCl 2 + Na2CO3 :rarrow: CaCO3 + 2NaCl

Just a test on my message formatting

After all, that’s what this thread is for, isn’t it? I think this thread should be a sticky, but hey, I’m too knew around here to make such suggestions. Even though I’ve lurked here for a long time. Just a thought.

Mass Relationships of Simple Compounds of Nitrogen and Oxygen

           Compound Total Mass (g) Mass of Nitrogen (g) Mass of Oxygen (g)

Oxide A     3.28                             1.00                             2.28
Oxide B     2.14                             1.00                             1.14
Oxide C     1.57                             1.00                             0.57


Possible Molecular Formulae for Nitrogen Oxides
Assuming that:

                          Oxide C is NO            Oxide B is NO              Oxide A is NO
                       
Oxide A is                 NO4                     NO2                              NO
Oxide B is                 NO2                     NO                                N2O
Oxide C is                 NO                       N2O                              N4O
