greetings to the members. I have to analyse miRNA (microarray data). i have downloaded the .CEL.gz files. however, i am unable to import them using affy for background normalisation. I am not sure which part have i missed. Kindly guide me Thanks a lot!
This is the R script i have used
library(affy) #path to load CEL files mirna <- "home/eshwari/Documents/GSE120356" list.celfiles() #import the files datafiles <- ReadAffy(celfile.path = mirna)
this is the error I keep getting.
(Error in read.celfile.header(as.character(filenames[])) : Is /home/eshwari/Documents/GSE120356/GSM3398822_N1.CEL.gz really a CEL file? tried reading as text, gzipped text, binary, gzipped binary, command console and gzipped command console formats)
