Users should be aware that when this is done, that highest q^2 ceases to be a valid test statistic for the significance of the model and no longer accurately reflects the expected external predictivity, just as is the case for variable selection methods in general( see U Norinder J. Chemonetrics 1996, 10, 95-105 and recent reports by other groups). This is because compounds are no longer completely "left out" of the analysis - each contributes to identifying the highest q^2. A lattice shift represents a random perturbation of the CoMFA descriptors. Though neither the highest nor the lowest q^2 value are of interest in and of themselves, the AOS and APS programs may nonetheless be useful for determining the distribution of values and hence how robust a particular model (the scheme used to align each molecule with the others) is. When this is done, however, the appropriate test statistic is the median or mode q^2 or, better, the mean cross-validated standard error and the q^2 calculated therefrom. Lattice placements which give q^2 values at either extreme - high or low - are misleading and therefore undesirable. It turns out, however, that good representative lattice orientations can reliably be obtained simply by applying ORIENT BEST to a prototypical molecular (usually the most extended of the more active compounds) and aligning other molecules in the training set on that prototype (RD Clark, M Cline & TW Heritage (1998) Making 3D QQSAR Both Simple and Robust, 215 ACS Natl Meeting, Abstract COMP 057). In fact, this is now the default option in the DATABASE ALIGNMENT dialog in SYBYL QSAR. Bob Clark Tripos Inc. 1699 S.

(http://www.gaussian.com/parallel.htm), G98 is available for Shared Memory Parallel execution on [Intel] Linux systems. Does anyone have G98 set up like this, and could report some performance results? I am particulary thinking of a Dual-P II 450MHz system, with G98 compiled with the Portland Group compilers, and using the tuned BLAS libraries as recommended by Gaussian, Inc. (see http://www.gaussian.com/g98_req.htm). This should be about the fastest *inexpensive* G98 implementation on x86/Linux at this time. (One can certainly get higher perfomance by using Linda with >2 CPU's, and/or Xeon processors, but either option would increase the cost substantially.) If someone has this setup and could run some benchmarks for me (should be < 1 h), I'd appreciate. Please contact me directly. I'll summarize for the list.

Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Dear Friends [and Enemies (:-)}], The holiday season has arrived. For many of us, it is time of joy but also reflection. Some of us are more reassured at the end of this year, and some are more humble; some are at peace with themselves, and some are busily searching. We already know that one cannot be happy without suffering first. We also know that nothing lasts forever. The change is what makes it all fascinating. In any way, life is a process (we, chemists know what process is, don't we?, though let us not talk about equilibrium at this moment, and beside, the true equilibrium is never reached, there is this quantum stuff and these 11 or so dimensions, which can leap us always to some new state, and let us face it, we do not know anything, we are stupid...), and the greatest value of this process is that each year brings new experience and makes us richer as unique beings which cannot be cloned. Each year makes us closer to the ideal of our creator (even if you refuse to personalize a creator, you have to admit that nature in itself is quite amazing, and will keep us employed for a long time to come...). We may never be sure why, but it is great to be a part of this constant struggle of reason and feelings, and fail to control our basic reflexes and know what others will do. [this is not a voice in discussion for or against impeachement, though...]. It is fun to be infinitely more unpredictable than cellular automata or neural networks and jump up and down. Consider the alternative... This is really better. So use the time to have some joy, forget about logic, be a party animal, and ask the questions later... The Y2k bug is a year ahead, so you will be able to read your e-mail when you come back from holiday break... Do not worry, be happy... Happy Holidays and the best of everything now and later...
