Hi,
  I got the following error when I try to do separate channel analysis of two color data.
  I did't do any background correction.
  How can I correct this problem?
   
> corfit <- intraspotCorrelation(MA.pAq, design)

  Error in intraspotCorrelation(MA.pAq, design) : 
        Missing or infinite values found in M or A

  Thank you so much for your help.
