Hello,
first time for me to work with SNP arrays. I got CEL- and CHP-files for my Analysis. The CEL are from Affymetrix Human-Wide Genome SNP- Array 6.0 and the CHP- files are dealed with the Birdseed- Algorithm (part of the Genotyp Console from Affymetrix as well).
Is there anybody here, who worked with this arrays in the past? I am looking for an (general) workflow for my study. I want to analyse patients with Rheumatoid Arthritis with regard to SNPs and the question "why there are respoonder and non-responder for the therapy"?
I am looking for an workflow for the arrays. Is it better to work with the CHP files or with the CEL- files? 
Would me great, if anybody can help me out.
Thanks in advance
Peter
