Hi I would like to know if there is any tool to work with affy SNPs chips. I have looked in the mail archives and it appears that some people were interested in it, so if somebody has any piece of code to share with me I would very very much appreciate it. If not, if somebody has created the cdfenv for the 10K (v2) chip, could I use it to read the cel files trought Read.affy ? thanks in advance ..

There are no tools currently in BioC specifically designed for analyzing Affy SNP chips. However, there is a group of us that is actively working on designing a package to do so. As for building a cdfenv using the 10K chip, you can use the devel version of makecdfenv for this. > > Mayte -- James W.
