  • Annotating heatmaps

    Does anyone have a good tool to annotate a heatmap based on functional group annotations rather than gene name. I am looking to cope with the case where you have too many genes to display the gene name but want to give a summary of what the various blocks coordinated expression contain.

    Thanks

    Hi Tom,

    have you tried gitools (http://www.gitools.org/home)?

      Just assign each functional group of interest a color and then use that with the RowSideColors option of heatmap(). If you're using heatmap.2 in the gplots package then it's the same option.

      Assuming you're using R of course.

        Thanks I will try both of those options

          Recent Advances in Sequencing Analysis Tools
          by seqadmin


          The sequencing world is rapidly changing due to declining costs, enhanced accuracies, and the advent of newer, cutting-edge instruments. Equally important to these developments are improvements in sequencing analysis, a process that converts vast amounts of raw data into a comprehensible and meaningful form. This complex task requires expertise and the right analysis tools. In this article, we highlight the progress and innovation in sequencing analysis by reviewing several of the...

          Essential Discoveries and Tools in Epitranscriptomics
          by seqadmin




          The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...
