Glatiramer Acetate Cheminformatics Problem and Fifth ChemInfo Retrieval Class - http://usefulchem.blogspot.com/2009...
Glatiramer Acetate Cheminformatics Problem and Fifth ChemInfo Retrieval Class
Polymers are where the problem with assuming that chemistry is structure centric come home to roost of course. Nico Adams has been looking at developing ways of describing polymers effectively and it really isn't straightforward. The whole notion of substance, chemical, and structure get very very messy. - Cameron Neylon
What is distressing is that someone added that initial obviously incorrect SMILES and it propagated easily to all those databases. As Tony has said many times curation is a big challenge in chemical databases. - Jean-Claude Bradley
I'd say the cause of everyone blindly copying data, is that they are happy enough to be able to copy data at all... it all starts with Open Data and the right to fix things, and share those fixes... - Egon Willighagen
+1 Egon - Cameron Neylon
I'm not sure that the reason people are copying data are because it's Open. PubChem continues to proliferate yet it is NOT Open. We've had this exchange before..PubChem is NOT Open data but I "judge" it gets copied because people treat it as an authority. It is not a good idea to treat PubCHem as an authority as it is a repository...non-curated and with no efforts underway to curate it... more... - Antony Williams
I agree that PubChem should not be treated as authoritative, but the big advantage it has over ChemSpider is that it can be downloaded and re-used. - Michael Kuhn
I agree that people copying PubChem is indeed not because it is Open... that one is copied merely because it is free and confuse that with Open. That said, I love to see the day that there was a court ruling on that state of the PubChem data, which is at some places claimed to be Public Domain, something refering to the copyright being with the providers, while at other places... a bullet proof statement would be *very* useful indeed. - Egon Willighagen
Michael - there is every intention to provide access to the ChemSpider structure collection in the near future. This will not include all associated information in a record as the associated information has mixed licensing but free to use. - Antony Williams
ChemSpider and Wikipedia have the advantage that errors can be corrected. Are there mechanisms in place to correct errors in DrugBank, PubChem and the many other derivative databases? - Jean-Claude Bradley
DrugBank: yes, David Wishart is said to be quite responsive to comments. Same for KEGG. PubChem: NO. They just aggregate tons of source databases, and you would have to hunt down the source and hope it makes it way downstream... Thus ChemSpider's annotation efforts are invaluable, and I would love to be able to re-use them - Michael Kuhn
Michael...drop me an email at antonyDOTwilliamsATchemspiderDOTcom and let's discuss how you want to use information and what you need to get at and it might be an issue of simply pointing you to the right web services. Lots of people are using ChemSPider through web services at present. We'd love to help you - Antony Williams
Chemistry in Second Life republished on PubMed - http://www.ncbi.nlm.nih.gov/pmc...
Article on Chemistry in Second Life by Lang and Bradley published in Chemistry Central Journal automatically republished in PubMed. Gotta love Open Access. - Jean-Claude Bradley

Evaluation of ultra performance liquid chromatography Part I Possibilities and limitations - http://acawiki.org/Evaluat...
One of my students used AcaWiki to summarize her chosen paper on ultra performance liquid chromatography and did a great job summarizing each paragraph. - Jean-Claude Bradley
looking for guest speakers for my Chemical Information Retrieval class: librarians, chemists, publishers, Open Access, impact factor, database folks, etc - duration 45-60 mins - will use screen sharing technology for remote talk - any takers?
When is it? - Egon Willighagen
maybe! when? what do you want them to know? if it's about *retrieval*, a reference librarian will probably do better by you. - D0r0th34
I have 4 slots - all Thursday evening at 18:00 ET Nov 5, 12, 19 and Dec 3 Dorothea we already had our ref librarian Peggy Dominy present - I'm looking to expand my students' horizons with issues of the day - these are some of the issues we're covering http://getcheminfo.wikispaces.com/FAQ - Jean-Claude Bradley
I am impressed, Jean-Claude! That's an excellent page. Let me think about it -- not sure what I have to add to that! - D0r0th34
Nice page indeed... though... my first impression with Chemical information Retrieval was the retrieval of data, not literature... but, yeah, I am a theorical chemist... :) - Egon Willighagen
Dorothea - it would be fine to expand on any of the items on the FAQ - or topics related but not covered already - the librarian's perspective would be very valuable - hopefully we can make it a fairly interactive session as well - Jean-Claude Bradley
Egon - the course covers issues relating to finding and disseminating chemical information. Since much of the data comes from the literature we spend a lot of time on how to find it there. - Jean-Claude Bradley
Yes, I know... I just talking the other day about linking database content to papers... so that a userscript will show what data from a paper is available for a certain DOI... - Egon Willighagen
Jean-Claude, we have rather different definitions of primary, secondary and tertiary sources. Where do yours come from/how did they develop? For example, to me, a peer-reviewed review article is a primary source in that it meets all the criteria: the researcher is the author; it is peer-reviewed; it is highly transparent; it makes an original contribution (reviews contribute in 3 ways:... more... - Mickey Schafer
Oops -- saw the Penn State links! I just don't agree with them. My definitions are mostly worked out with my local ref librarians, so I will stick with them for the time being. But it does make me wonder if it isn't perhaps time to re-work definitions a bit? I have a difficult time telling students that their original take on an item is of lesser value because they didn't generate the... more... - Mickey Schafer
Egon - it is always helpful to have the link from data to source. ChemSpider does this for experimental values (mp, bp, density, etc). Wikipedia is frustrating - I tried to find the primary source for a mp last week and couldn't because there is only a general bibliography - and many of the references are not even online. - Jean-Claude Bradley
Mickey - all of the FAQ are student answers and we would welcome any discussion. In this case I think the definition of primary and secondary sources matches my experience with the terms. A primary source is the ultimate source of the information. Review articles are secondary sources because they discuss data generated in primary sources. Do you have an alternative definition that we can read from your librarian contacts? - Jean-Claude Bradley
Will need to formulate something...meaning, that I normally write this stuff up on blackboard as part of an in-class exercise. The whole question though is an interesting example of potentially useful g-wave uses...a student and I are using it to converse (sort of), and it seems that a conversation about a particular topic/question set at a specific time using g-wave could result in... more... - Mickey Schafer
Mickey - the problem with using Wave for an FAQ is that there isn't a convenient way to make it public - Jean-Claude Bradley
I was thinking of creating FAQs based on what came up in the wave, and as a way of generating short posts on teacherly topics. - Mickey Schafer
ok I see Mickey - Jean-Claude Bradley
am posting this to my local network of people interested in information literacy - we are running a project here as you speak (I will try and get the ringleader to contribute to yours if the time doesn't translate to 3am here ...) - Anna Croft
thanks Anna - let me know - unfortunately my time slots are fixed at the time when the class meets - Jean-Claude Bradley
yeah, figured as much :) Just forwarded on your scivee stuff as well - Eileen will think this is great! (and finally we might get some support from the centre to do things) - Anna Croft
Anna - good it would be nice for those videos to get some use outside my class - Jean-Claude Bradley
Cheminfo Retrieval Fifth Class FA09 - http://www.scivee.tv/node...
Cheminfo Retrieval Fifth Class FA09
The fifth Chemical Information Retrieval class at Drexel University on October 22, 2009 started out with covering the new 3D structure viewer introduced recently at PLoS ONE to provide ideas for students doing a multimedia project this term. The current student answers to the chemistry publishing FAQ are then discussed. The reason for removing glatiramer acetate from ChemSpider is explained and a few databases (Wikipedia, PubChem, DrugBank) are visited that still contain the incorrect SMILES, 3D structure and related properties. An overview of an Open Access site (OAD) suggested by Bill Hooker is provided to suggest additional questions for the FAQ. Examples of questions discussed include primary and secondary sources, peer review, article level metrics (a PLoS ONE article on malaria is used as an example), citation searching, Impact Factors and whether one should use one's real name in the blogosphere. Databases Scirus, Web of Science and PubMed are also reviewed. - Jean-Claude Bradley

Pascal Lapointe - Ce texte est paru initialement dans l'édition de novembre 2008 de la revue Découvrir - Jean-Claude Bradley
first time I've seen a French translation of "Open Notebook" = "carnet de notes libre" - Jean-Claude Bradley
Lapointe: "Pourquoi attendre un an quand on peut entamer un dialogue qui se mesure en semaines, voire en jours?" - ff: heures :-) - Claudia Koltzenburg
Somewhat strange conclusion: "Bémol : dans notre société, le journaliste est le seul à pouvoir creuser un problème controversé sans risquer d’être accusé de conflit d’intérêt. Si on se réjouit de voir des scientifiques jeter un pont vers un public élargi, en parallèle, on a toutes les raisons de s’inquiéter de ce qui subsistera, dans 30 ans, d’une information scientifique libre et... more... - Daniel Mietchen

Sixth Cheminfo Retrieval class: What is the m.p. of strychnine? - http://usefulchem.blogspot.com/2009...
Cheminfo Retrieval Class Six FA09 - http://www.scivee.tv/node...
Cheminfo Retrieval Class Six FA09
This is the lecture from the sixth Chemical Information Retrieval class at Drexel University on October 29, 2009. It starts with a review of some of the new questions answered by students from the chemistry publishing FAQ, which covers patent information and accessing electronic journals at Drexel. Tony Williams submitted a puzzle to resolve conflicting structures in ChemSpider, which is too difficult to be a regular assignment. It requires re-analyzing spectroscopic data in papers where stereochemical assignements are determined. An example is paromomycin which has three entries. The regular assignment for the week is then introduced and it involves obtaining 5 different sources each for 5 different properties for a molecule of the student's choosing. To demonstrate how to do the assignment strychnine is chosen as an example. Melting point information is obtained from ChemSpider (ultimately MSDS sheets), Wikipedia, Wolfram Alpha and in a JACS article via SciFinder. By investigating... - Jean-Claude Bradley
Webcite can be used to archive an Excel version of the Solubility Summary spreadsheet - here is the Nov 3, 2009 archive: http://www.webcitation.org/5l12V0P... All formulas and web services called are retained - they would not be in other formats such as CSV. This will work with any Google Spreadsheet - convenient for formally citing a database
Now that's good to know! - Cameron Neylon
That's brilliant. - Andrew Lang
I just uploaded another version - notice how it gives you a dropdown for the cached version on the top right. You can now create a hyperlink to a specific cached version like this http://www.webcitation.org/query... - Jean-Claude Bradley
Brilliant stuff. I'm becoming a big fan of WebCite - will use the service for the bulk of the Web refs in my thesis. The versioning functionality may come in handy. - 'Mummi' Thorisson
Mummi - I had experimented with it a long time ago and there were some issues that led me to drop it. There are still issues - for example when they alert you to the fact that your submission is archived they don't give you all the citation information - have to remember to copy and paste all that info given on the website itself right after submission. I also don't know what happens to... more... - Jean-Claude Bradley

Chemistry in Second Life paper in Chemistry Central Journal
My Xstreet account has seen a very sharp uptake on the number of people getting our stuff. I have had to log in to SL just to make sure my messages are not capped. I'm sure it will die down soon but pretty cool to see. - Andrew Lang
where is the best place to find source code for these items, is http://opensledware.wikispaces.com/ still active? great article, congrats! - Mike Chelen
Last time I checked the wiki was mainly taking spam. I think Desideria Stockton runs it and she's not been inworld a lot lately afaik - Peter Miller
The final format just got published http://journal.chemistrycentral.com/content... which is nice because you don't have to download the pdf for the full text version - Jean-Claude Bradley
It's great Anthony! I put it up on the ONSclaims page as the first animated gif http://onsclaims.wikispaces.com/ (for some reason I image Andy's orac (or a Dalek) speaking the words as they pop up) - Jean-Claude Bradley

Open Chemical Data #1: NMRShiftDB - http://chem-bla-ics.blogspot.com/2009...
some 'open data' on ChemSpider. - Andrew Lang
what would be the best way to mirror the data and interface, is nmrshiftdb-data-1_3_4.sql.gz and the applet all that is needed? - Mike Chelen
Egon would be the person to ask about that - Jean-Claude Bradley
Mike, I guess it depends on how you like to mirror it... you could talk to Christoph Steinbeck in setting up a node in the NMRShiftDB network... alternatively, you could simply make the data available using a custom (read-only) web interface. I recently starting offering the NMRShiftDB data (GNU FDL license) as RDF triples, now mirrored by, for example, Bio2RDF... - Egon Willighagen
Egon: hopefully something that can be downloaded and reused or modified, would it help to bundle the SQL and RDF data together with the applet? - Mike Chelen
I think you can download the whole lot from sf.net/projects/nmrshiftdb, but never installed the full thing myself... - Egon Willighagen

Representation of Molecules and Molecular Systems in Data Analysis and Modeling - http://www.goodreads.com/review...
Egon Willighagen's thesis is a must-read for chemists who seek to understand the emerging role of cheminformatics. The topics covered include molecular chemometrics, molecular descriptors - with an emphasis on those derived from NMR spectra, and crystal packing modeling. There is a strong emphasis on the sharing of Open Data and Open Standards, detailed in the description of the Blue Obelisk Repository. Novel methods of disseminating chemical metadata - such as CMLRSS - are highlighted. Most of the chapters have been published as separate articles and are available from links provided on the chem-bla-ics blog: http://chem-bla-ics.blogspot.com/2008... - Jean-Claude Bradley
Thanx Jean-Claude! - Egon Willighagen
no problem Egon - it was very enjoyable - Jean-Claude Bradley
Email me your address if you like a copy. I still have a few around :) - Egon Willighagen

looking for speakers for Visualization of Chemistry at ACS - Jean-Claude Bradley
are there any presentations planned about SL sculpted proteins, or the molecule rezzer? - Mike Chelen
Andy and I will do something with the orac rezzer - probably will show off some proteins with Andy's sculptie trick. Will you be at ACS Mike? - Jean-Claude Bradley
sounds cool, definitely would like to be there, will recommend anyone attending try to catch the session. also, if there are any materials such as more documentation or code that gets released, that would be interesting for all users to hear about. would be happy to try and collect or share some more info if it would be helpful - Mike Chelen
Mike - probably the best summary from Andy and myself is this article on chemistry in SL with a link here until the review process completes http://usefulchem.wikispaces.com/SLchemP... - Jean-Claude Bradley
Mike did you want to present something at ACS? - Jean-Claude Bradley
Jean-Claude: wow great paper! love figure 6, that was made by combining models from the protein rezzing toolkit with sculpted proteins right? this looks very complete, trying to think if there is anything else interesting to add? - Mike Chelen
Mike - yes Andy created that by combining Peter Miller's protein rezzing toolkit with his 1-prim sculptie - Jean-Claude Bradley
Jean-Claude: that combo of protein rez toolkit and sculpty is really great, are there any other topics or examples that would be helpful to see more of? - Mike Chelen

Interactive 3D Visualisations of Biological Molecules Integrated into the Scholarly Literature - http://usefulchem.blogspot.com/2009...
Downloaded from Oxford and installed OK for me under Vista. Data download for the paper was (unsurprisingly) slow on home wifi and browser (Ff) failed to close on first attempt but eventually up and running without problems. Slightly sad that we are back to ugly frames but otherwise nice (this from someone who is not a structural biologist). - Peter Miller
Hope to see similar animation capabilities soon for other visualizations (particularly imaging data), as described for Adobe PDF files at http://www3.interscience.wiley.com/journal... and for TeX-based PDF at http://www.ctan.org/tex-arc... . - Daniel Mietchen
sounds just great, for attribution matters, how will reference to a certain point in such a process work? http://ff.im/8HPXx - Claudia Koltzenburg
@JC Downloaded the patch to run on my XP OS with no glitches at all. - Graham Steel
I didn't have problems with the helper app but a little worried that the whole thing seems heavily dependent on what seems to be proprietary code. Why not use protein explorer? - Cameron Neylon
Why does an Open Access journal use Closed technologies?? - Egon Willighagen
My hands are itching in making a Open solution for this... - Egon Willighagen
The authoring component also costs which will limit its educational use too. - Peter Miller
+1 Egon - we're working with a couple of computer science students to do just that. - Andrew Lang
Bora has a video which could help those with trouble downloading the plugin see what this is about http://everyone.plos.org/2009... - Jean-Claude Bradley
ok - got it to work finally. Works as advertised. It feels a lot like Jmol - Egon is that what you would use for an Open solution? It is a bit surprising that PLoS ONE went with a non OA solution. Bora can you disclose the reasoning? Is there really no free authoring component? - Jean-Claude Bradley
It worked ok for me but crashed on exit. - Andrew Lang

I'm sure they could be trained to use weapons, maybe other stuff too - maybe we could use mice for crowdsourcing - mousesourcing? - Andrew Lang
All kidding aside it would be cool to play Quake against mice. They don't seem to be harmed by running in the maze. Of course I'll be playing the side of the cats :) - Jean-Claude Bradley

Cheminfo Retrieval Fourth Class FA09
This is a recording of the fourth class on Chemical Information Retrieval on Oct 15, 2009 at Drexel University. It starts with some tips on removing formatting from Wikispaces pages, the Drexel Cisco VPN client for accessing paid subscriptions off campus and how to link to a DOI. The first two assignments for the class are then described. The first involves summarizing each paragraph of an article and an option to use AcaWiki is demonstrated. The second involves filling in an FAQ for publishing in chemistry. FriendFeed is then presented as a resource to help answer questions followed by an extensive overview of available information on ChemSpider, covering SMILES, InChIs, InChIKeys, experimental and predicted properties, linked databases and contributed spectra. Finally a demonstration of Beilstein Crossfire is presented with an emphasis on doing substructure searching. - Jean-Claude Bradley
