raw expression matrix in eset.rds from Celegans.Tintori.Cello does not contain integer values

Hi, 

I opened the file eset.rds `obj<-readRDS(eset.rds)` from the github repo Celegans.Tintori.Cello but find that `obj@assayData$exprs` is not a raw count matrix since the values are not integers. Could you help me check that? I need the raw count matrix to do some computational analysis. 

Thanks!
