Hi Everyone, I need to submit some affy chip data (Mouse 430 2) to GEO. This is an old project that I picked up from someone else, and I have the .CEL files, but no .CHP files. GEO seems to really want .CHP files. Is there a way to generate them from .CEL files? Or is there an alternative that someone can recommend? Thanks, Janet Smith

CEL files contain the raw data. That should be on GEO. With CEL files and a complete verbatim description/code of the analysis one can ideally regenerate the results. CHP files contain processed signals/summarized signals/parameter estimates - not raw data. CHP files are typically generated by Affymetrix software tools only. If your analysis was using, say, Bioconductor tools, you never generated CHP files. If so, it doesn't make sense for GEO to ask for them.

Janet, Use the GEOArchive option to deposit Affy data to GEO. Download the Excel template from GEO and fill in data as required. You can easily upload your own processed values for your experiment.

I completely agree with Scott on this, i've tried all the GEO methods & GEOArchive is by far the easiest Mark On 02/11/2010, at 7:37 AM, Ochsner, Scott A wrote: > Janet, > > Use the GEOArchive option to deposit Affy data to GEO.

Thanks all - GEOArchive is indeed much better than the GEO Submission page. No need for .CHP files anymore... good. - Janet ________________________________________ From: Mark Cowley [m.cowley@garvan.org.au] Sent: Monday, November 01, 2010 5:21 PM To: Ochsner, Scott A Cc: Janet L Smith; bioconductor at stat.math.ethz.ch Subject: Re: [BioC] Generating .CHP files from .CEL files I completely agree with Scott on this, i've tried all the GEO methods & GEOArchive is by far the easiest Mark On 02/11/2010, at 7:37 AM, Ochsner, Scott A wrote: > Janet, > > Use the GEOArchive option to deposit Affy data to GEO.
