Graphics converter
by Jonathan W. Steed 21 Jul '97

21 Jul '97

Dear all, apologies for the *slightly* un-web-related topic but does anybody know of a conversion utility which will turn a Silicon Graphics .RGB file (as in captured from an IndyCam) into something Windows can read (ideally .GIF or .JPG but I'll take any common PC format; WMF, BMP, CLP etc etc)? My excuse for asking this here is I want to put the pictures on my web page! Many many thanks for all advice. Jon. Dr. Jonathan W.

atomic structure time line
by buescherl＠watertown.k12.wi.us 19 Jul '97

19 Jul '97

Dear chem web subscribers; I have recently put together a simple time line for my high school chem students. It deals with the development of the modern atomic theory. It is very brief and my intention was to show students that it took many scientists working in several related fields, many years to develop the theory. Your thoughts and suggestions would be greatly appreciated. The site is at http://www.watertown.k12.wi.us/teachers/buescher/atomtime.html I enjoy this list serve and have used several items with my students.

MacMolecule2/PcMolecule2
by Paul May 17 Jul '97

17 Jul '97

Hi, You might be interested to know about another 3D molecular viewer that I've just come across. It's called MacMolecule2 (the Windows equivalent is PCMolecule2) and can be used as a helper application to open pdb and other format files. There is also a freeware version of these programs, known as MacMolecule2 lite and PCMolecule2 lite. They can be obtained from the University of Arizona at: <http://www.molvent.com> They have many features that I haven't seen in other some viewers (such as Rasmol & WebLab), such as including a sidebar which contains text about the molecule allowing a scripted tutorial as the student views the moelcule in different orientations.

Compatability testing for Chemical Web Browsers
by Rzepa, Henry 16 Jul '97

16 Jul '97

I have produced a small matrix of tests for various Web browsers and versions for some chemically relevant web pages. http://www.ch.ic.ac.uk/compat.html I am seeking further examples of pages which perhaps fail on one browser but work on another, or fail on one version but work on another. Do please send me good examples if you have them. I don't have any ActiveX examples, or non-Javascript examples, so please send those. Also, any dissenters for my claims are most welcome! Failures by the way should be reproducible. Plain old browser crashes which occur at random are too dependent on machine configurations and memory allocation to be really useful. Finally, I might note that in our hands IE 4 fixes a number of problems with Chime, Javascript and other features of IE3. Dr Henry Rzepa, Dept.

WebMasters 3 - access counting
by Mark Winter 11 Jul '97

11 Jul '97

Dear colleagues A number of issues were raised at the WebMasters 3 meeing yesterday, one of the less important of which is access counters. Many of you will have full analyses of your own log files but interesting snap shots of user profiles based upon hits on a single page can be quite informative. I've been playing with a few external services in the last month or so and the following are worth a look. Both free. There are current links on the framed WebElements home page [http://www.shef.ac.uk/~chem/web-elements/] 1 NedStat: http://www.nedstat.nl/ This is an interesting one because it gives you a break down of accesses by country/continent/hour/day/month Try: http://www.nedstat.nl/cgi-bin/viewstat?name=webelements to see what you get. The disadvantge is all the info is in Dutch but if, like me, you can't read a word, it's still pretty clear what's going on. 2 WebSide Story: http://www.hitbox.com/wc/world.html Interesting because it tells you unique accesses, reloads, and can be monitored in real time using a java contoller. Try: http://w12.hitbox.com/wc3/index.cgi?G25025119 to see what you get. If you create your own counter using the "science" category with this service, it will be located in the "high tech" area. With these two types of counter, if you are desparate to maximise hit rates, put the requisite HTML high on your page. Numbers are about 10-20% lower if contained towards the bottom of a longish page. ---- [PS - general applause for Becky Allen for all the hard work organising the meeting; the RSC who have backed the WebMasters meetings from a very early stage in WWW history; and to Karl Harrison for all the hard work involved locally at Oxford in hosting the 1997 meeting] Dr Mark J Winter (Deputy Head of Department) Department of Chemistry, The University, Sheffield S3 7HF, England tel: +44 (0)114 222 9304 fax: +44 (0)114 222 9303 e-m: mark.winter(a)sheffield.ac.uk http://www.shef.ac.uk/~chem/staff/mjw/mark-winter.html WebElements is the periodic table on the world-wide web: http://www.shef.ac.uk/~chem/web-elements/ The Sheffield Chemdex is a listing of chemistry sites on the world-wide web: http://www.shef.ac.uk/~chem/chemdex/ chemweb: A list for Chemical Applications of the Internet.

I mentioned in my posting about chemical sketchers that some of them might require user registration to use. I am happy to correct that the Tripos one in fact can be accessed without such registration; ie >Thank you for mentioning our Java sketcher in your letter published via >chemweb on Tuesday, July 8.

Use of Java for chemistry
by Rzepa, Henry 08 Jul '97

08 Jul '97

There appears to be a significant momentum in the creation of interesting Java applets for Web use. Some relatively new to me are http://mc2.cchem.berkeley.edu/Java/ (small applets illustrating color) http://www.chimie.fundp.ac.be/javas/he_dz_java.html (a full blown SCF calculation on the helium atom) Lots of new molecular sketchers, including one ACD labs have kindly let us use for the ECTOC-3 conference http://www.ch.ic.ac.uk/ectoc/ectoc-3/mol_search_java.html and this one http://daylight.daylight.com/pmsp/ which is the fastest I have thus far seen. There are of course many other chemistry Java applets out there, but they seem to be hidden behind web pages that require registration (free or otherwise, such as http://www.java.isolnet.com/java/java_invds.html or http://www.tripos.com/discovery.net/top.html ) I certainly recommend also seeing e.g. the MSI Gene/Polymer explorer modules if you can get a demo. I also note that a new form of technology (programs written in C++ or other "old languages, but surrounded by a so-called CORBA wrapper and placed onto a CORBA server) can be accessed by Java applets in the client-server model. This allows server-side computations to be performed without the performance hit that Java sometimes imposes. Any good examples of this form of computing again please post to this forum. Finally, I note http://www.odi.com/ which mentions the adoption of a technology called PSE in Netscape and IE browsers. This is a so called "persistent object store", which in effect (as I understand it; elaborations welcome) can be used to create an object database out of Java classes cached by your browser on your hard disk. This sounds like a mechanism for greatly reducing download times for Java applets, and a technology which gives much room for thought (if it can be done for Java, why not for chemistry!!). If anyone comes across other molecule sketch programs or other interesting Java applets, do please post to this list. We try to maintain a chemistry list of these things at http://www.ch.ic.ac.uk/java/ Dr Henry Rzepa, Dept.

browser profiles over the last 18 months
by Mark Winter 08 Jul '97

For your interest I enclose percentage browser stats for the last 18 months. There's all sorts of reasons why these numbers aren't scientific but the apparent trends are interesting anyway.

About 5000 variants of browsers were logged over the 18 months - but only 1400 were active in the last 3 months! NetScape Version 3 use is still increasing (at the expense of version 2). Version 4 is only increasing slowly - perhaps chemists are not inclined to use it because of problems involving it and CHIME? MS InterNet Explorer (all versions) is rising and is now nearly 20%. More than 97% of all hits are NetScape (v2 or better) + MSIE (all versions) so it appears barely worth bothering to use other than these for site testing.
