What Does R/S Refer To In These Rna-Seq Files?

Question

[Radhouane Aniba]

Hello everyone,

I went through GEO fishing for RNA-seq datasets to play with and I came through this one

In the download section there is mentioned :

GSM754335_R_RNA_GM12878.bam.gz
GSM754335_S_RNA_GM12878.bam.gz

Does R/S refer to PLUS and MINUS strand ?

Thank you

My guess, since they are trying to construct a diploid genome to look at SNPs, is that R and S might be "reference" and "snp", like when R/S is used for dbSNP accessions. Just a wild guess, could be totally wrong!

This seems like a question for the Gerstein lab.
