NMR Interest Group / Metabolic profile by NMR spect: 79 10*27 combinations possible
I am also having this kind of problem with my QSAR work. I have 37 molecules and nearly 300 descriptors to build a meaningfull QSAR model. According to my searches and reading there are many ways to select right combintaion. For examaple Statistica software has a function to choose variable form a list based on their probablistic possiblities. But some times it does not work.
\"Genetic Algorithms\" which combinies variables to select best subset is the best solution. As far as I know older versions of Statistica is capable with it.

Mass Spectrometry Interest Group / Column Type
According to my experience Phenomenex columns are better but Waters columns are best. Shimpack is also good but sometimes you can not get what you want. I recommend you to buy Phenomenex.
