Hi, Guido. The output of sessionInfo() might be helpful (or not). It is certainly possible that this is an issue with GEOmetadb, but the error suggests that RSQLite might be to blame, also. I'd suggest reinstalling RSQLite as a start. If you still have issues after doing so, definitely include the output of sessionInfo().

Hi Sean, The reason i did not include the output of sessioninfo() was because my R session hangs. Anyway, below the output after loading GEOmetadb, but BEFORE running any other commands.

Hi Sean, Indeed, you are correct! Due to my inexperience with performing database queries, and clumsy interpretation of some example code I inadvertently closed the connection to the database... Well, after omitting this line the example is working fine now! :) One thing though, through GEOmetadb I locate 17751 CEL files for GPL96, whereas a query directly @ GEO indicates it hosts a considerably larger number of these arrays (i.e. Samples (28011)). Any idea what may cause this discrepancy? http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GPL96 Thanks again for your assistance, Guido -----Original Message----- From: seandavi@gmail.com [mailto:seandavi@gmail.com] On Behalf Of Sean Davis Sent: Thursday, June 30, 2011 14:03 To: Hooiveld, Guido Cc: bioconductor (bioconductor at stat.math.ethz.ch); Seth Falcon Subject: Re: [BioC] R crashes with GEOmetadb See below.

GEO has not always required raw data. As an aside, the GEOmetadb database is update often, but not continuously, so there will be a bit of a lag (sample numbers may be lower in GEOmetadb than in GEO proper).
