    My experiment is complicated (at least in my mind =) ). I have three time points (0,24,48 hrs) and two conditions (siControl and siTarget) for a total of 6 groups. I'm trying to see how knockdown of my target affects the transcriptome at each time point.

    This information is the closest I can find online that describes how to make a log2-fold change heat map and a dendrogram.... but I'm having some troubles. Can anyone please help?

    A few questions so far:

    1. sigGenes <- getSig(cuff,'BY4741','ino80',alpha=0.05,level='genes')
    -Why were only two of your groups selected here and not the whole data set? Does this impact the final result?

    2. db <- logFC(db,mutants=mut,WT=WT,logBase=2,pseudo=1)
    -when i enter this, I get an error message: Error in db[, mutants] : incorrect number of dimensions

      Sorry clicked too fast...

      Sorry I should add that so far I have done this:
      >WT<-"C1"
      > mut<-c("C2","C3","C4","C5","C6")

        Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
        by SEQadmin2



        Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

        Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

        New Genomics Technologies Take Aim at Long-Standing Limits
        by SEQadmin2


        Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

        We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
