Incorporating 'offset' into edgeR pipeline
... Hello All, I would like to adjust my RNAseq dataset for GC content. I used EDASeq to calculate the offset. Code data <-newSeqExpressionSet(counts=as.matrix(d$counts),featureData=feature,phenoData=data.frame(pheno),row.names=rownames(d)) dataOffset <- withinLaneNormalization(data,"gc", whi ...

Tools for classifying reads from xenograft samples?
... Hello All,  I must separate human and mouse RNAs obtained by RNAseq from a tissue after xenotransplantation (human NSCs to mouse model).  Would you please suggest Bioconductor or other tools for classifying reads from xenograft samples? What is the recommended read depth and length for this kind o ...

Comment: C: RNAseq with technical replicates: Does it sound right?
... Hi Ryan, Thanks for your reply.  I would like to clarify it further. Are you suggesting that having many files with lower counts as technical replicates and then combining them (adding up the raw counts of  3 files)  is a  better way to go than having one  file with  ~ 30 million reads. Along thos ...

I expected 36 files with ~30 million reads. Instead, I got 108 files (18 samples/per lanes with ~ 10 million rea ...
