I am getting an error running simpleaffy on some moe430a chips: > qc <- qc(exp1.all.raw,exp1.mas5) Error in qc.affy(unnormalised, ...) : I'm sorry, I do not know about chip type: moe430acdf > exp1.all.raw AffyBatch object size of arrays=712x712 features (47532 kb) cdf=MOE430A (22690 affyids) number of samples=12 number of genes=22690 annotation=moe430a > sessionInfo() R version 2.1.1, 2005-06-20, i386-pc-mingw32 attached base packages: [1] "tools" "methods" "stats" "graphics" "grDevices" [6] "utils" "datasets" "base" other attached packages: simpleaffy limma siggenes qvalue "2.0.13" "2.0.2" "1.2.17" "1.1" gcrma moe430aprobe matchprobes affy "1.1.4" "1.1" "1.0.22" "1.6.7" reposTools moe430acdf moe430a annaffy "1.5.19" "1.5.1" "1.8.5" "1.0.18" KEGG GO Biobase "1.6.5" "1.6.5" "1.5.12" Back on January 19th, Crispin Miller told me that this was probably fixed in simpleaffy 2.07. I'm hoping someone could check this out again, or notice what I am doing wrong. Thanks very much, Dick ********************************************************************** ********* Richard P.
