Hi, We are just beginning to use the limma software, specifically with the GUI interface and are running into some problems. Our array has duplicate spots in a top to bottom manner. When we try to have Limma calculate a duplicate correlation we get the error message "Error in package_version(vers) : invalid version specification". Any help or suggestions in addressing this road block would be greatly appreciated. Thank you, Manish Neupane

Hi Manish, Please tell us the platform and versions of the software you are using. The best way to do this is to type sessionInfo() at the R prompt and copy and paste the output to your email, thanks, Keith Satterley Manish Neupane wrote: > Hi, > We are just beginning to use the limma software, specifically with the GUI interface and are running into some problems.
