  • Normalized Values from DESeq2

    This is the raw table example of my data but....

    Gene Name Mutant Mutant Mutant WT WT WT
    A 2343 2341 2842 1549 1303 1123

    Can I get a table that has these normalized from DESeq2

    is this correct? or is this for the previous version of DESeq


    normalizedCounts <- t( t(counts(dds)) / sizeFactors(dds) )

      Code:
      counts(dds, normalized=T)

        Thank you

        Those two codes give the same results... Do you know why when I take the normalized to values and perform a log2fold change it is not the same as in DESeq2 log2foldchange


        1.) take average of three replicates for mutant
        2.) take average of three replicates for wt
        3.) log2(mutatnt) - log2(wt)

        This comes close to DESeq2 log2fold change but not quite the same...

          It'll be a little off due to fold-change shrinkage (i.e., your calculated values should generally be larger).

            Indeed that is the case.

            Thank you

              Current Approaches to Protein Sequencing
              by seqadmin


              Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

              Strategies for Sequencing Challenging Samples
              by seqadmin


              Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
