Message-ID: <70e4a94e23605eb96238018fd5476e47@videotron.ca> For an article I'm writing, I need to be able to generate an image of the 3D structure of a moderately complex chemical such as a simple protein. In fact, a sequence of half a dozen amino acids would more than suffice. I don't need to draw any specific molecule(s); I'm just trying to illustrate a few different levels of abstraction, starting with "realistic" (the 3D molecule) and working my way up the chain of abstraction to the base triplets that encode the amino acids. Clip art could work, but I'd rather generate the image myself to avoid any potential copyright entanglements. Lots of stuff turns up in Google, but before I spend a few hours spelunking and testing, I thought I'd look for personal recommendations from people who have actually used the software. Criteria: I'm looking for something free (I almost certainly won't use it again), free of copyright entanglements, easy to use, and able to produce a crisp image that would ideally also work in black and white or greyscale. System requirements: I'm on a Mac using OS X (Panther, not Tiger). A browser-based tool would be fine.

I say: It's been awhile since I've used any of this, but I used to work for MDL, which offers a free drawing package called ISIS/Draw. To download it, you need to register at their Web site. It used to be a good program, but that was about 8 years ago. Good luck!

Message-ID: Yesterday, I asked for suggestions on tools to help me draw a moderately complex chemical structure. Since the respondents proposed a range of tools, each of which will meet different needs, I haven't explored each tool and presented a recommendation. I'll do that myself later for my own specific needs, with the proviso that YMMV. That being said, here's my summary based on a quick glance at the recommended resources: There are many professional-tools available for scientists, not all of which are accessible to those who only play one on the Internet. For non-professionals (as opposed to unprofessionals ), there are several alternatives. Electric Rain provides a range of tools for 3D illustration (http://www.erain.com/downloads/trials/), also available in trial versions. These don't seem to be directly dedicated to chemistry, but may be useful if you want full control and are comfortable with a "roll your own" solution. Similarly, the VTK (Visualisation Toolkit, http://vtk.org/) also appears powerful, but not a dedicated application for chemistry. Adept Scientific's ChemDraw (http://www.adeptscience.co.uk/download/dldcat/22/0/All/ChemDraw.html) looks promising, and will run on Mac and Windows. ADC's Chem Sketch (http://www.acdlabs.com/download/) also looks cool, and is free for home/educational use, but a quick look suggests it's Windows only. That won't fly on my Mac. MDL's ISIS/Draw (http://www.mdli.com/downloads/): Didn't take the time to register and check whether it'll run on my Mac, but Google suggests that it will. Rasmol and OpenRasmol (http://www.rasmol.org) also appear promising, and are open source software that should run on Mac, Windows, and Unix. Ditto for PyMol (http://pymol.sourceforge.net/pmimag/screen.html). The University of Illinois' Visual Molecular Dynamics software (http://www.ks.uiuc.edu/research/vmd) seems to be a power tool for real molecule geeks, and runs under Mac, Windows, and Unix. ETH Zurich's MOLMOL software (http://hugin.ethz.ch/wuthrich/software/molmol/) falls into the same category, but seems to be Windows/Unix-only. The aforementioned geeks may also appreciate the links at the Protein Data Bank site . Clip art may also be an option, but I'll use it as my last resort to avoid any copyright issues. If I draw the molecule myself, then barring any software licensing agreements to the contrary, copyright won't be an issue. Thanks to Heidi Arnold, Cathy Arthur, Deborah Ausman, Debra Bissantz, Sandy Harris, Rob Hodgins, Joe Malin, and Iwan Thomas.
