I would... first thing I do when people report that the CDK has a bug is to validate what they input. At least in 20% of the time (very conservative estimate) it is bad input. - Egon Willighagen

Answer by Egon Willighagen for Generate 2D sdf/mol files from SMILES (for 2D depiction of structures) - http://blueobelisk.stackexchange.com/questio...
Rajarshi was written a convenient helper program using the CDK to create a PDF from a SD file: Batch generation of 2D diagrams After downloading the draw2d.jar, you can do: java -jar draw2d.jar your.sdf It has several command line options to tune the output: usage: draw2d [OPTIONS] sdf_file Draws 2D images from coordinate files. Default output is PNG and input should be an SDF file. -c,--scale Scale factor (default is 0.9) -f,--format Output format (PNG, JPEG, PDF) -h,--help Give this help page -l,--color Color atoms -n,--ncol How many molecule columns should tabular output have. The number must be 1 or more -o,--outputDir Where to dump images (default is current directory) -p,--props If present output properties in the PDF table. Default is no -s,--showH Show explicit hydrogens (default is no) -t,--table Output structures as a tabular PDF. This option overrides the format option and the output file is called output.pdf -v,--verbose Verbose output -x,--x Width of the images (default... - Egon Willighagen

Wordle for "The 2010 Nucleic Acids Research Database Issue" (Titles minus 'Database')
A comprehensive update on the human protein resource - Frank from iPhone
"update" looks very popular :-) - Duncan Hull
And I doubt these updates will have to do anything with APIs... where's RDF in that wordle?!?! - Egon Willighagen
Egon, It was just made with the titles of the articles. Anyway, the word "RDF" doesn't appear in the abstracts - Pierre Lindenbaum

Sarah Palin kicked out of hospital fundraiser in Canada. Palin has said that "Canada needs to dismantle its public health-care system and allow private enterprise to get involved and turn a profit" - http://www.reddit.com/r...
It's amazing how some US citizens can be so blind to not see where market economy fails... free market requires buyers to be able to decide, "no, perhaps when you lower your price..." But it just does not work like that for health care... or housing... there does not exist something like a free market when basic needs are involved... - Egon Willighagen
health care, housing: these are 'constrainted' markets... you just can't decide, no, let's not have a new kidney this year and wait until the market is better... no, let's use boxes this year until the house prizes have dropped a bit again... - Egon Willighagen
Egon, you have put your finger on the worst thing about the US (imo, as a recent immigrant). It's not so much that citizens are so blind as that the kleptocracy in power understands your point completely, and completely does not care. Government of the people, by the rich, for the rich... I just hope for the revolution to be a "velvet" one when it comes. - Bill Hooker
@Egon, I'm hardly an expert on policy issues, so I don't pretend to necessarily know best, but market failure doesn't necessarily mean a non-market solution is best; if anything it suggests that the focus should be in finding a way to establish a competitive market as to prevent a government from having too much influence over private citizens. Some ideas that I'd like to see evaluated... more... - Benjamin Tseng
Problem is that consumers lack the specialized skill to properly evaluate health care choices that means an expert ie The Gov must mediate the choices and provide regulations to preent the consumer from being unwitting victim same as they license doctors and lawters they must regulate teh healthcare indistry - WarLord
"given that the American system "works" broadly speaking" -- that stretches "broadly" to breaking point imo. Have you ever "been without health insurance" (honest term, "failed to pay the required protection money") in the US? - Bill Hooker
@Bill, I'm not going to pretend the American system is perfect (b/c it isn't), but almost all employed people in the US have healthcare that they are satisfied enough with such that they're not willing to take their chances on a public option; that doesn't mean I condone the failings of it with regards to access or equity, nor does it mean I wouldn't experience hardship if I lost my job... more... - Benjamin Tseng
@Benjamin, fair enough -- I can't pretend to be a policy or market expert either. I am also not exactly an impartial observer, being for the moment without health insurance in the US! (I spent my first 30 years in Australia, so my experience of a public option is that it has its problems too, but nothing like the massive systemic failures of the US system in its current form.) - Bill Hooker
@Bill, I'm sorry to hear that :(. Does your employer not provide coverage? I thought you were at a biotech firm? - Benjamin Tseng
"When there's a problem with your car engine, you fix the engine, you don't necessarily replace the whole car" Unless the engine was damaged because another part of the car is malfunctioning due to being poorly laid out. Many people can't switch coverage because of "pre-existing conditions" even though their current insurance is severely lacking in coverage and customer service. The... more... - Heather
Benjamin, I can point to a specific example (and I have always been covered and found the US system substandard). When you go to the ER, you could get billed the full amount for an emergency procedure, just because the doctor you saw wasn't contracted with your insurance company at that particular ER. Last I checked, when you go to the ER for an emergency procedure that's not what you... more... - Deepak Singh
@Benjamin -- we're working on it. I should have said "temporarily" or similar. Can't explain in detail -- public company disclosure blah blah blah. Suffice to say I'm not being exploited, and didn't want to give that impression! - Bill Hooker

How do I validate if my MDL SD file is correct? - http://blueobelisk.stackexchange.com/questio...
The CDK used to have a library to validate chemical graphs against common problems, including unknown atom types. Additionally, the file reader for the MDL SD format has a STRICT mode, which makes it fail if the file is not conform the format. However, the CDK currently does not have a library of command line utilities that make functionality available. What Open Source tools are available to inspect the file and the content of a MDL SD file, and report errors? - Egon Willighagen
Egon Willighagen
Wondering if #CiteULike calculates #impactfactors for journals... (or #connotea, or #mendeley, ...)
it would surely be just an estimate, but the error because of the data set may not be higher than the general error on impact factors... (which is an interesting question in itself...) - Egon Willighagen
I don't understand the point. Journal-level metrics are obsolete. - Björn Brembs
@Björn: the context is this question on the Blue Obelisk Exchange: http://blueobelisk.stackexchange.com/questio... - Egon Willighagen
I don't mind about the actual metric used, but automating generation of such lists would be nice... - Egon Willighagen
@Björn: I am very much open to suggestions from your side! - Egon Willighagen
As I mentioned on Twitter, Mendeley does generate article and journal-level usage stats, on a daily basis. This data will be available via API, as well, starting soon. Let me know if you'd like to know more about this. - Mr. Gunn
@Mr Gunn... yes, such an API would be perfect. I'd like to hear more about that... - Egon Willighagen

Pierre - are you saying the exam was hard? :) - Jean-Claude Bradley
Are the answers online too? In particular that for question 16... - Egon Willighagen
THREE CHEERS FOR JEAN-CLAUDE. - D0r0th34
The answers are all in the FAQ question 16 about ACS policy on self-archiving and gold access is FAQ 14 http://getcheminfo.wikispaces.com/FAQ - Jean-Claude Bradley
and actually that question about ACS self-archiving came directly from a FriendFeed conversation with the kind help of Graham and Dorothea :) http://ff.im/buFyT - Jean-Claude Bradley

Open Notebook Science in undergraduate education. A former student in our ONS class is linking to his notebook in his graduate school applications. - http://openwetware.org/wiki...
Another example of a good unintended consequence of using ONS in undergraduate lab courses. He is a star student and did outstanding work. Clearly has a successful research career ahead of him. It's only anecdotal evidence, but I have to think that the fact that he's linking to his ONS coursework means that he's likely to be more open with his future research (when he's able to). - Steve Koch from Bookmarklet
@Steve... indeed... but soon he'll realize that Open Collaboration in a world where everyone is closed is not so easy... we're chem/bio informaticians are in a luxury situation in that respect... - Egon Willighagen
Just out of curiosity, Steve, what kind of guidance did the student receive in terms of the writing itself? I like his style -- energetic (stylistically, this means he writes in mostly active sentences, uses passive correctly yet more sparingly than is typical in published scientific prose), confident (a stylistic result of grammar and vocab choice: in this case, few hedge words used... more... - Mickey Schafer
Great! It is an easy way to stand out from the competition - especially if your work is high quality - Jean-Claude Bradley
@Mickey I'm guessing you were looking at his "final" formal report on electron diffraction. I think the short answer is that my guidance had little impact on his good writing. You can see his rough draft (http://openwetware.org/wiki...) along with my comments at that time in the margins. I do try to push the students to write in an ill-defined... more... - Steve Koch
@Egon, I do spend a lot of time talking with the students about the reality of scientific practice as it stands today. In fact, I tell them, something like, "if you continue in research, you're more than likely going to have to practice closed science. And you may even have to write things down by hand in a paper notebook! Having been through this class is going to make you hate that... more... - Steve Koch
The quote I use with my senior undergrads doing thesis writing with me: ""For those who reach maturity with their natural curiosity intact and enhanced by education, the joy of discovery is a strong driver of success. The joy of research, however, can be fleeting or at best fickle." --W. Franklin Gilmore, President Sigma Xi - Mickey Schafer
Steve, Egon -- I guess it's true that most science is still practiced in a closed fashion, but my feelings about whether students should be exposed to the idea has changed a lot during the last year. Now, I think it's sort of mandatory that at least one person explain the option (along with OA as a publishing strategy) b/c I think it is this generation that will have to make... more... - Mickey Schafer
Steve - I think your guidance is right on track. Those who are learning to work openly (to whatever degree) are at a significant advantage for finding positions with groups who value that approach - but they are also qualified for traditional "closed" positions with the added benefit of being able to show their potential future employer what they are capable of doing in their public... more... - Jean-Claude Bradley

Who can point me to a drug where tautomerism is involved in its mode of action?
I heard of warfarin having functional implications due to tautomerism, did you checked that ? - Khader Shameer
No, but will do so now... thanx for the pointer! (others: more ṕointer always welcome) - Egon Willighagen
Enol tautomer as biological switch - http://www.ncbi.nlm.nih.gov/pubmed... - Neil Saunders
Surprised that "drug tautomer" only throws up 96 PubMed records - many of which are computational studies (docking etc.) Perhaps > 1 tautomer under physiological conditions is rare? Or avoided by design? - Neil Saunders
Hate to be a pedant, but do you mean that a less thermodynamically favourable tautomer of a drug is the bound/active form? - Matthew Todd
@Matthew: our group is writing a book on pharmaceutical bioinformatics (cheminformatics, QSAR, proteochemometrics), and we are trying to have all examples pharmaceutically relevant... tautomerism is a source of variance in cheminformatics (as is pKa, resonance structures, conformations, ...), so discussed in the book... any effect of tautomerism on drug activity would be good enough - Egon Willighagen
@Neil you got a DOI? Your PubMed page does not link anywhere at uu.se and Google Scholar does not give hits on the title other than PubMed... - Egon Willighagen
PDF would do fine too of course... first.lastname _at_ gmail :) - Egon Willighagen
@Egon That's odd. No DOI - reference is Adv Exp Med Biol. 2003;527:601-8. Can't get PDF. Best I can do is this Google book link - http://bit.ly/78w6rV. - Neil Saunders

NCBI RSS feeds now gives me a link to "79 new articles" instead of one article per RSS item... :-(
When number of new articles per check exceeds certain amount, NCBI provides only links. - Pawel Szczesny
yep , it happens to me as well. I assume that Pawel is right that there is some number above which it reports a link instead of individual items - Pedro Beltrao
It's from here: http://www.ncbi.nlm.nih.gov/bookshe... "If the number of citations retrieved is greater than the number of items displayed the feed will include a link to display the complete PubMed retrieval." - Pawel Szczesny
Nice polymorphic API! They could also stick with one API and output more RSS entries in that case. - Egon Willighagen
ah, ok. Thanks Pawel. - Pierre Lindenbaum
