Dear Pedro and list

	I encountered an error message upon filtering an RMA normalized object.

 > ddPROC=filterMicroRna(agiMicro.rma,
+  agiMicroraw,
+ control=TRUE,
+ IsGeneDetected=FALSE,
+ wellaboveNEG=FALSE,
+   limIsGeneDetected=50,
+ limNEG=25,
+  makePLOT=TRUE,
+ targets,
+  verbose=TRUE)
FILTERING PROBES BY FLAGS


FILTERING BY ControlType
Error in data.frame(as.character(PROBE_ID), as.character(GENE_ID),  
as.character(probe.chr),  :
   arguments imply differing number of rows: 644, 0

The relevant portions of my script up until that point are:
###################################################
library("AgiMicroRna")
targets<-readTargets("Targets.txt",verbose=TRUE)
agiMicroraw<-readMicroRnaAFE(targets,verbose=TRUE)

agiMicro.rma=rmaMicroRna(agiMicroraw,normalize=TRUE,background=FALSE)

ddPROC=filterMicroRna(agiMicro.rma,
                     agiMicroraw,
                     control=TRUE,
                     IsGeneDetected=FALSE,
                     wellaboveNEG=FALSE,
                     limIsGeneDetected=50,
                     limNEG=25,
                     makePLOT=TRUE,
                     targets,
		    verbose=TRUE)
###################################################

Please advise.

Thanks and best wishes,
Rich
