Cannot able to find a particular column in R

0

While importing data from a database(ArrayExpress) using this -

anno_AE <- getAE("accessionid", path = raw_data_dir, type = "raw")
sdrf_location <- file.path(raw_data_dir, "accessionid.sdrf.txt")
SDRF <- read.delim(sdrf_location, stringsAsFactors = FALSE)
rownames(SDRF) <- SDRF$Array.Data.File

After this-

SDRF <- AnnotatedDataFrame(SDRF)

Cannot able to find column 'Array.data.file' in SDRF

How to solve this issue?
