I use library(EBSeq) for differential expression analysis, When I run EBOut=EBTest(Data=ebvRna1,Conditions=condition1,sizeFactors=sizes, maxround=5) got an error message: Error in EBTest(Data = ebvRna1, Conditions = condition1, sizeFactors = sizes, : Please add gene/isoform names to the data matrix But I checked my Data by str(ebvRna1) int [1:395, 1:20531] 2 2 2 2 2 2 2 2 2 2 ... - attr(*, "dimnames")=List of 2 ..$ : NULL ..$ : chr [1:20531] "LOC100130426" "UBE2Q2P3" "UBE2Q2P3.1" "LOC149767" ...

It looks I have the gene names for my matrix. Does anyone have any ideas about this?

Thanks a lot, Lilly
