There are times when being able to download the data used to create a publication is very useful. Perhaps you want to compare interesting data to some of your own. Or you may want to analyze the data differently than the original author to try and gain additional information. Or perhaps you’d just like to check out the data yourself that the author’s conclusions are valid. For my “tip of the week,” I thought I’d give you a tip for downloading some of that data from NCBI’s GEO (or Gene Expression Omnibus) database. We’ve got a whole introductory tutorial on how to use GEO, but this ~3 minute screencast will show you how to easily get GEO information into an Excel spreadsheet. Hope you find this tip as useful as I did when I learned it!
