Dear list, Now I am using Illumina Human 6 BeadChips. But I found the annotation file is old. They used hg18 gene symbols. e.g. CRSP6 should be MED17. http://www.ncbi.nlm.nih.gov.ezp-prod1.hul.harvard.edu/gene/9440 KIAA0804 should be VPS8 http://www.ncbi.nlm.nih.gov.ezp- prod1.hul.harvard.edu/gene/?term=KIAA0804 But I found the annotation file downloaded from here cannot match the probe id. http://www.switchtoi.com/annotationprevfiles.ilmn Anyone have suggestions? Thank you. -- Best wishes, Jinyan HUANG
