Hello, I am looking for a function or package to import the "Detailed sample annotation" file from the ArrayExpress Database. For GEO there is the "GEOquery" package. For ArrayExpress there is the "ArraExpress" package. But I am looking for a function to import or read the "xxxxxx.sdrf.txt" file. Is there something? Thanks Markus -- Dipl.-Tech. Math.

Hi, I found a working solution: an <-read.table("E-GEOD-635.sdrf.txt", header=TRUE, sep="\t") Best Markus Markus Schmidberger schrieb: > Hello, > > I am looking for a function or package to import the "Detailed sample > annotation" file from the ArrayExpress Database. > For GEO there is the "GEOquery" package.

Hi Markus, This is effectively working. Another alternative is that the sdrf.txt file content is fully contained in the phenoData of the object created by the use of the ArrayExpress function from the ArrayExpress package.
