I'm trying to download DNA methylation data from GEO to learn how to use Rnbeads package. I didn't have a problem downloading data sets ( I've downloaded this one https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE38240). Unfortunately, I couldn't find the sample sheet for the dataset above or any other dataset.
A sample sheet with Sentrix_ID,Sentrix_Position is essential for loading the data. Can someone tell me where to find the sample sheet of a given GEO dataset ?
