Dear All Having read the GEOQuery documentation, there are commands which fetch SERIES files from the web and convert to ExprSet, and there are commands that take a GDS and convert to ExprSet - however, for some reason, my R connection to NCBI works only in about 20% of cases - connections to all other websites are fine - and I simply want to get the file myself (SOFT or SERIES, I don't mind), store it locally and open it in getGEO and convert to an ExprSet object. Is that possible?

With everything except GSEMatrix, it is possible. See the filename argument in getGEO. I am adding GSEMatrix file parsing in the near future. Sean

I have added GSEMatrix file parsing to the devel version of GEOquery. It should be available in a day or so after the build system gets through with it. Sean
