    Yeah, bioinformatics can be quite frustrating... Although, the feeling is great when you get it done and you see all those beautiful tables with genes, aligned with p values and so on

      Hey guys, is there an extra step needed for DESeq to adjust for library size?

      What I mean is, I have three replicates, and two of them have half as many reads as the first.

      So my file after pasting it into Excel, looks like this

      Untreated Treated
      Gene 1 6 3 3 8 4 4
      Gene 2 10 5 5 12 6 6
      .....

      I then use this table to use for DESeq. Does DESeq adjust for each sequencing depth?

        This is covered in the DESeq vignette, see also the "estimateSizeFactors" command, which is part of the standard work flow.

            Advancing Precision Medicine for Rare Diseases in Children
            by seqadmin




            Many organizations study rare diseases, but few have a mission as impactful as Rady Children’s Institute for Genomic Medicine (RCIGM). “We are all about changing outcomes for children,” explained Dr. Stephen Kingsmore, President and CEO of the group. The institute’s initial goal was to provide rapid diagnoses for critically ill children and shorten their diagnostic odyssey, a term used to describe the long and arduous process it takes patients to obtain an accurate...
