Data processing |
Analyzing 250K Nsp and 250K Sty chip CEL files by Affymetrix Genotyping Console v4.1, we obtained the probe level intensity data for all match and mismatch probes. We applied quantile normalization to probe level ratios a=PMA/MMA and b=PMB/MMB. Then for each probeset or SNP, we computed the allelic intensities A=max(mean(log2(a)), 0) for allele A and B=max(mean(log2(b)), 0) for allele B based on the normalized ratios a and b. Finally, we obtained the total intensity A+B for each SNP on the 250K Nsp chips and the 250K Sty chips. The intensity data from two kind of chips were combined into one file. The AplusB8GMs3types.ns.txt matrix file contains the total intensity data. It has 25 columns and 500568 rows. The Affymetrix SNP ids are in the first column. The rest columns contain 3 assays for each of the 8 CEPH samples.
