I tried micro array analysis by R library "affy", but I got error like this.
eset <- mas5(hoge)
background correction: mas
PM/MM correction : mas
expression values: mas
background correcting...Error in getCdfInfo(object) : Could not obtain CDF environment, problems encountered:
Specified environment does not contain HuGene-1_1-st-v1 Library - package hugene11stv1cdf not installed Bioconductor - hugene11stv1cdf not available
So, I decided to use oligo instead of affy. (there was also warning to use oligo or xps)
I just want to normalize by either mas5 or RMA, and then out put normalized CEL file as text file.
Does anyone know how to do above proccess by "oligo" ?
Also, if there is good website about this proccess by oligo, please tell me that URL.
Thank you !
