I am trying to query RNA seq datasets (GSE117271 and GSE117403) by using the GEOquery package, but it doesn't work.
The code is here. It works for microarray data rather than this RNA seq data:
GSE117271 <- getGEO(GEO = "GSE117271", destdir = "GEO sets", AnnotGPL = T)
Annotation GPL not available, so will use submitter GPL instead Using locally cached version of GPL18573 found here: GEO sets/GPL18573.soft Warning message: In download.file(myurl, destfile, mode = mode, quiet = TRUE, method = getOption("download.file.method.GEOquery")) : cannot open URL 'https://ftp.ncbi.nlm.nih.gov/geo/platforms/GPL18nnn/GPL18573/annot/GPL18573.annot.gz': HTTP status was '404 Not Found'
GEO help desk told me that
GSE117271 and GSE117403 contain sequencing data (and not microarray data). Such studies do not have Sample data tables, and so the GEO Series Matrix Files (which are downloaded by GEOquery) do not have processed data.
Is this why it doesn't work? Or the arguments should be changed? Are there other functions or packages to query such RNA seq data in R?
Thank you in advance for your help and ideas!
