Normalizing For Batch Effect In RNA-Seq Data

Hello,

Does anyone have a suggestion for dealing with "batch effect" between two batches of small RNA-Seq data? I've heard "ComBat" was good. Anyone have any others in mind?

Thanks in advance.

The EdgeR package in Bioconductor can help with this. See the Arabidopsis data set in the User's Guide where samples were collected at different times.

Thank you. I will give it a look over.

Try RUVseq, they have three different approaches how to deal with batch effects based on empirical genes, in-spike genes and samples contrast. Also, take a look on PEER.

I used combat and it does it pretty well.
