Hello, I am an absolute beginner in using bioconductor. I would really appreciate some help if you have time. Thanks very much in advance. I have been trying to access a GSE file from GEO using GEOquery. I got the same error message as reported by David Martin on 8 June 2010. > gse <- getGEO(filename = system.file ("extdata/GSE20080_family.soft.gz", + package = "GEOquery")) Error in read.table(con, sep = "\t", header = FALSE, nrows = nseries) : invalid 'nlines' argument In addition: Warning messages: 1: In file(fname, "r") : file("") only supports open = "w+" and open = "w+b": using the former 2: In file(con, "r") : file("") only supports open = "w+" and open = "w+b": using the former 3: In file(fname, "r") : file("") only supports open = "w+" and open = "w+b": using the former > I think the archived help file is here https://stat.ethz.ch/pipermail/bioconductor/2010-June/033876.html It mentions file location... Sorry, I'm not sure how to resolve this problem with file location... Do I need to download the file from GEO first? Sorry for being so ignorant. Thanks a lot.

You have the right function, but what you are doing above will try to load data from a file on your computer. Just do: gse <- getGEO('GSE20080') This will fetch the data from NCBI GEO.

Thank you so much! The GUI now reads File stored at: C:\DOCUME~1\AdminNUS\LOCALS~1\Temp\Rtmp4MN2u9/GPL8490.soft Warning message: closing unused connection 3 () > Will I be able to use the methylumi package to read and analyse this type of data? Sorry, I read through the methylumi pdf but could not really find out how to start using data downloaded from GEO. Sorry again for being stupid.
