Dear all, I just start learning aroma.affymetrix package for Affy SNP6.0 analysis. I downloaded ugp,ufl,acs file from the link http://www.aroma-project.org/chipTypes/GenomeWideSNP_6, followed the example code, but I got the following warnings. I can't move to the following steps. Would you please let me know what the problem is?
Thanks a lot, Qian > cdf <- AffymetrixCdfFile$byChipType("GenomeWideSNP_6",tags="Full"); > print(cdf); AffymetrixCdfFile: Path: annotationData/chipTypes/GenomeWideSNP_6 Filename: GenomeWideSNP_6,Full.cdf Filesize: 470.44MB Chip type: GenomeWideSNP_6,Full RAM: 0.00MB File format: v4 (binary;
