Dear all,
         I have a data set where there are two samples, each with four replicates. I have created a DGEList object with the relevant count data. While executing the command: 
estimateCommonDisp(Massed_Spaced_Isoform.DGEList, rowsum.filter = 1)
I get the following error:
"Error in if (mx < tol) { : missing value where TRUE/FALSE needed"
The traceback() output is:
3: estimatePs(object, maxr)
2: equalizeLibSizes(object, disp = disp, null.hypothesis = FALSE)
1: estimateCommonDisp(Massed_Spaced_Isoform.DGEList, rowsum.filter = 1)

      Please advise.
     Thanking you.
