For reasons I will not go into, I came across this current awareness publication. Its both printed, and available as http://www.senn.com/ Its not free, but they claim "site licenses" are available (senn(a)world.std.com) I wonder how many central or chemistry libraries have current subscriptions to such publications? The reason I though it might be worth evaluating is that in the next "issue" (April) they claim they will be focusing on Chemistry Resources. March is devoted to Molecular Biology. In the current issue, they also look at top quality sites, and what made them so. Certainly, we all have lessons to learn from the best sites! Finally, I might note that I spotted no advertising in the March issue. ----- chemweb: A list for Chemical Applications of the Internet.

Converting Mac Chemdraw images to PC gif images. How?
by Paul May 01 Mar '96

01 Mar '96

Hi, At Bristol, we have the unfortunate situation of the Organic and Inorganic Depts using Macs, while we in Physical Chemistry (including me, the webmaster), use PCs and UNIX. So when I have to create web pages for staff members in org/inorg chemistry, I keep on running into the problems of (a) converting their Mac files to PC-readable ones, and (b) converting their Mac Chemdraw diagrams into gif files. The text is just about do-able, but I'm having real problems converting the Chemdraw files. The best I've come up with is to get the author to print out a good quality hard copy, and I scan it in using Windows formatting. But there must be a better way!! Does anybody know of a simple utility program, or method, that will allow me to do this without all the faffing around? ----------------------------------------------------------------------------- Dr Paul May, School of Chemistry, University of Bristol, UK tel: +44 (0)117 9287667, fax: +44 (0)117 9251295 email: paul.may(a)bris.ac.uk WWW: http://www.bris.ac.uk/Depts/Chemistry/staff/pwm.htm "Another squashed hedgehog in the gutter of the information superhighway" ----------------------------------------------------------------------------- ----- chemweb: A list for Chemical Applications of the Internet.

ChemDraw files are binary-compatible (i.e. completely compatible) on all three platforms. Make sure that it has a .chm filename extension and a ChemDraw file created on the Mac should be directly readable into the Windows or UNIX versions of ChemDraw. For conversion to GIF on the Macintosh side, we generally recommend using the freeware clip2gif application. It does a really nice job. Also, recent versions of ChemDraw (3.5 or later, I think) include an AppleScript that allows you to create a "Save As GIF..." menu item. We use clip2gif for on-the-fly GIF creation at http://chemfinder.camsoft.com and we have also in the past used it for batch translation of files. A really nice little program. Supports JPEG and TIFF, too. The options for GIF creation on Windows are significantly more limited.

Save the Word file as RTF, use RTF2HTML (shareware application) to convert the whole file into html, and at the same time spit out the figures/pictures as PICT files, and then use CLIP2GIF to convert the resulting PICT files into GIF files (as its name suggests it convert the clipboard file or any PICT file into a GIF file). This is quite neat since RTF2HTML produces html which contains <IMG SRC...... commands which expect GIF files. You could equally use CLIP2GIF to convert a Chemdraw picture one at a time into a GIF by cutting the picture from Chemdraw (hence making it the clipboard file) and then getting CLIP2GIF to do its work.

IUPAC recommendations on WWW
by G.P.Moss 01 Mar '96

01 Mar '96

International Union of Pure and Applied Chemistry (IUPAC) Nomenclature on World Wide Webb The first of several planned IUPAC nomenclature recommendations have been converted into a World Wide Webb document which can be accessed from your desktop. The "Glossary of class names of organic compounds and reactive intermediates based on structure. Recommendations 1995" [Pure Appl. Chem. 67, 1995, 1307-1375] can now be consulted from: http://www.qmw.ac.uk/~ugca000/iupac.html This contains over 700 class names with over 1300 cross-links and 170 illustrations. Due to the nature of the medium the material is now fully indexed and the entries are ordered into 22 categories so that related material is together. The sections are hydrocarbons, ring systems, alcohols and ethers, aldehydes and ketones, carboxylic acids, compounds with one nitrogen atom, compounds with more than one nitrogen atom, compounds containing boron, halogen, metals, phosphorus arsenic or antimony, silicon or germanium, sulfur selenium or telurium, ions and radicals, natural products and miscellaneous entries. The natural products are subdivided into antibiotics, carbohydrates, lipids, nucleic acids, terpenoids, tetrapyrroles and other natural products. Due to the limitations of the html language some characters have to be converted into text e.g. Greek letters are given as [alpha] etc. However instead of just having a note that a term used in a definition is available elsewhere in the glossary there is now a link. Click on the word and the definition itself will appear. In addition to the glossary there is a full list of nomenclature recommendations from the Commission on the Nomenclature of Organic Chemistry (3.1) and also for the Joint Commission on Biochemical Nomenclature together with those of the Nomenclature Commission of the International Union of Biochemistry and Molecular Biology. There is also a link to the IUPAC data at Cambridge on the organisation of the Union.

chemdraw to gif
by G.P.Moss 01 Mar '96

01 Mar '96

I have no problem on the mac with chemdraw files if saved as a pict file. This can then be converted to gif by the shareware GraphicConverter. For the best effect I then set the background to transparent (from the colour setting). I have converted 100's of files this way on my IUPAC nomenclature Web pages which I will circulate details with a following message.

> At Bristol, we have the unfortunate situation of the Organic and > Inorganic Depts using Macs, while we in Physical Chemistry (including > me, the webmaster), use PCs and UNIX. Ditto!! However the WWW stuff is done on Macs so this is kind of an inverse problem...some of the following may therefore not be relevant. > The text is just about do-able, but I'm having real problems converting > the Chemdraw files. The best I've come up with is to get the author to My solution to the whole problem is not nice, but works. I use my PC to read in Mac files (eg Microsoft Word + embedded ChemDraw) which works ok. I then use Paint Shop Pro to cut out the images - drop them down to 8 bits and save as gifs. The rest of the processing is done on the Macs using Graphic Converter (resize, reduce res. to 72dpi, make transparent etc.) The good thing is that the Macs will read PC disks (if you have PC Exchange) and therefore anything I create on my PC can be read on the server (in fact I set my PC up as an FTP server and use Fetch on the Macs to pull over the images etc..) So... what does this mean for your problem? I guess that if you can get people to write their stuff on a PC disk that would help. Mac files with OLE information shouldn't present a problem. If you have Mac disks with only ChemDraw files, again they are readable by the PC version and you can cut and paste them into PSP when they are open. Sorry if this sounds a bit convoluted but it's almost going home time and I'm not ready for it...

MOTM
by Paul May 01 Mar '96

01 Mar '96

Hi, It's March, so we have a new Molecule of the Month, kindly provided by Alan Wilson at Birmingham. The direct address for it is: http://chemwww.bham.ac.uk/motm/motm.html or you can get to it (and all the previous MOTMs) from the MOTM Home page at: http://www.bristol.ac.uk/Depts/Chemistry/MOTM/motm.htm We have at least 3 more MOTMs in preparation, but that only takes us till the summer. So, does anyone fancy writing one for June or July?
