Chimera is available for Windows, Mac Aqua, Mac/X11, and Linux. The download includes full documentation and tutorials. Many improvements and new features have been added since the previous production release (Dec 2008), as listed in the release notes: http://www.cgl.ucsf.edu/chimera/docs/relnotes/1.4.html For the time-challenged, here are just a few of the reasons you may want to use the new version: 1) appearance: - friendlier initial display, similar to ribbons preset - CA-only and P-only structures can be shown as smooth tubes - rings can be filled, aromatic rings shown with circles - improved transparent surfaces (single-layer, etc.) - glossy lighting option on many platforms - anisotropic B-factors can be shown as ellipsoids - surface coloring by Coulombic electrostatic potential - 2D labels new font options, can be hidden/shown - labels can be moved with the mouse - improved single-sequence display - offscreen rendering on most platforms 2) I/O: - Blast protein tool uses Web service hosted by our lab; * hits can be shown as sequence alignment * corresponding structures (if any) can be retrieved - new fetch type EMDB with keyword search - can set download directory for caching fetched files - Gromacs 4 trajectories supported 3) analysis and editing: - planes can be defined from sets of atoms, used in distance and angle measurements (with atoms and axes) - many more options for volume data filtering, processing - new measure command performs several calculations on structures, surfaces, and maps - structure-based sequence alignment tool (Match->Align) can iterate to consistency 4) scripting: - improved movement commands (rock, roll, turn, move, reset), visual effect commands (surftransparency, set), new commands (coordset, fly, pause) for movie scripting - volume planes playback (volume command) - bond rotation (rotation command) - nucleotide displays (nucleotides) - symmetry copy generation (sym) - runscript command for running python scripts with command-line arguments See the release notes and User's Guide for more details.

However, I'd say that you have too little memory. Having two quad core cpus means you will have a total of 8 cores to run calculations and with only 4 GB you have an average of 500 MB per core. While that may be good for what you intend to do, if you plan on doing coupled cluster or something similar it will definitely not be enough. I'd say the minimum nowadays would be 1 GB per core, perhaps 2 GB if you can afford it. If you are going to do MP2 and above stuff I would then recommend 4 GB per core (if you can't afford that, I'd then invest on buying the memory in only a single DIMM (or two, for dual channel purposes) so that you can buy more later on. Saving money by buying 4x1GB RAM will be bad on the long run). As for the disk... once again it depends on the computations you are going to do and the way you will be using the servers. Will you try to use as much as possible 8 cpu jobs? Or do you think you'll have lots of 1 or 2 cpu jobs? If you run mainly 8 cpu jobs then it should be fine with one disk (you may want to have a bigger size though, if you plan on doing stuff that stores a lot of integrals [once again, high level ab initio stuff]). If you are going to run several jobs per machine I think you should try two disks as the I/O may become an even bigger problem that what it usually is (if different jobs are trying to access different parts of the disk you'll get lower performance). Hope this helps and if you could tell us a bit more about the kind of calculation you'll be running, perhaps other people will have a better insight.

Message-Id: <-40887-091208225522-6975-YnMH7SrytD1H++CQ9PnXyA-x-server.ccl.net> X-Original-From: "Tsung-Wen Yen" Date: Tue, 8 Dec 2009 22:55:18 -0500 Sent to CCL by: "Tsung-Wen Yen" [peter308(~)gmail.com] Dear CClers: My caluculation of Mulliken partial charge on noble metallic clusters(N=38) has some peculiar results. Some of the atoms will show 5~6 electrons. Is this reasonable? I used (RECP19|SD) basis set for Gold and Copper. Could you tell me on which range should be reasonable for MPA charges? I have the feeling my electron structure may have converged to a wrong state. I appreciated for your advice. Best Regards Tsung-Wen Yen
