[BioC] A question regardin duplicate correlations in limma

[Manish Neupane]

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
