I'm afraid HOMA it's not implemented in Gaussian, but its calculati= on can be done
on the back of an envelope, you only need distances and few constants.
This topic was already discussed in CCL. See e.g.:

you have to beware that a corr= elation does not necessarily establish a causality (wearing a particular co= lor wont increase risk of heart failure in humans although you can certainl= y inquire what is the color most often worn by people with heart attacks)

Dear Neeraj,

th= at's actually the underlying idea of any SAR or -getting quantitative- QSAR= study. Basically you must calculate any property  you can think of (i= n your case usingDFT, although why being so close minded?), and checking we= ther there are any correlation between the  properties you obtained an= d the bioactivity.

So the answer is yes, you can do it. Inet is plenty of= information about such approaches.

Antonio

However, my current cluster is not especially powerful and I feel it will not be up to the task. So, I am looking to buy and build a new machine. I have very little experience with running CPMD, so I am not sure about what kind of hardware requirements it has. I am planning to run CPMD calculations with something on the order of 200 to 400 relatively light atoms, primarily C, H and O. I do not need to run large quantities of simulations, and would be perfectly happy with only being able to run one simulation at a time as long as it is within a reasonable time scale. With this in mind, does anybody have any suggestions about what hardware I should be looking to use, especially which CPU? Also, would should be my primary concern with the cluster? I am currently assuming that the most important thing will be large quantities of RAM for each CPU... Any help or advice is appreciated.

Professor Murray-Rust's career spans academic positions in Stirling, Nottingham and Cambridge and the establishment of one of the earliest Molecular Graphics laboratories with Glaxo in the early 80's. More recently, he has become well known for his contributions to the Open Data movement and various Open Source developments, such as within the Blue Obelisk framework. In order to acknowledge Professor Murray-Rust's contributions to science we are now organizing this symposium. Everyone is welcome to attend, in particular of course the large number of people he has been involved with on a scientific, as well as a personal basis. Participation at the symposium is free, please just register your interest via e-mail with Susan Begg (smb28^-^cam.ac.uk) until the end of November. Best wishes and we are looking forward to welcoming you to Cambridge soon, Cheers, Andreas -- Andreas Bender, PhD Lecturer for Molecular Informatics Unilever Centre, Cambridge University http://www-ucc.ch.cam.ac.uk Personal: http://www.andreasbender.de From owner-chemistry@ccl.net Fri Nov 12 13:48:00 2010 From: "Bjoern Baumeier baumeier- -mpip-mainz.mpg.de" To: CCL Subject: CCL:G: XC potential matrix elements output Message-Id: <-43154-101112133631-20349-tvgWYgaXviiiv2ZuBR7q7g%a%server.ccl.net> X-Original-From: "Bjoern Baumeier" Date: Fri, 12 Nov 2010 13:36:29 -0500 Sent to CCL by: "Bjoern Baumeier" [baumeier|a|mpip-mainz.mpg.de] Hi people, does anyone of you know whether it is possible to output the matrix elements of the XC potential either in Gaussian or in Turbomole?

If that system has G03 and G09, be sure you are using the formchk utility for G09 by specifying the full path to the executable, for example "/software/gaussian/g09/formchk yourfilename" if the G09 installation were located in /software/gaussian. You can then read the .fchk file directly into GaussView on your Ubuntu machine, but keep in mind that certain output generated by G09 will not be compatible with GaussView3.
