Is SAS programming is necessary for Microarray data analysis??
R, which is basically the free version of SPSS which uses the [url=http://en.wikipedia.org/wiki/S_(programming_language)]S language[/url] and probably underlies SAS, is very commonly used, but I wouldn't call it "necessary". I used to work with a statistical physicist who worked on microarray data and he refused to use anything except FORTRAN!.
i think SAS programming is not necessary for Microarray data analysis
today, many softwares are available in the market for Microarray data analyzing and some of them are freely available and some of them are payable. R software is freely available at http://www.r-project.org/
Matlab sofware is payable
