software for expression matrix analysis - (Feb/20/2002 )

Hi all,
I am trying to write a small program in C to test out various algorithms for clustering expression data. The trouble is, that I cannot read in a typical data set (say, 70 experiments x 2500 genes) without getting various errors (my background in CS is limited)´. Can anyone tell me if there is an example of this kind of code available on the net to learn this from?
Thanks
Peter

Hi

I dont know if I am able to help you but what I know is that a lot of program analyse microarray are programmed in the langage R because they allready have a library for microarray....so perhaps you should try this langage or anyway perhaps you will find there some explanation about your programation problem. (I hope this helped you)

I have been analyzing micrarray data using Perl, mostly because I know Perl, while I don't know C++ well. Also, there's a lot of info about using Perl for bioinformatics data analysis on the web (see, for example, bio.perl.org), and there are a ton of modules available for Perl (see www.cpan.org).

cuca is right as well -- there are packages available for R (see www.r-project.org), but I don't program well in R, either...
