Dear Bioconductor List,

	I received an error message when trying to normalize data with  
AgiMicroRMA
 > agiMicro.rma=rmaMicroRna(agiMicroraw,
+ 		normalize=TRUE,
+  		background=FALSE)
Error in if (min(dd.aux$Rb) < 0) { :
   missing value where TRUE/FALSE needed
 > agiMicro.rma=rmaMicroRna(agiMicroraw,
+ 		normalize=TRUE,
+  		background=TRUE)
Error in if (min(dd.aux$Rb) < 0) { :
   missing value where TRUE/FALSE needed
