  • upper quartile normalization

    I'm sure this has been asked before, but does anyone know how to perform upper quartile normalization on RNA-seq data? I cannot find a script to do this and it seems like it should be a simple matter of getting the read counts for each lane and then normalizing (but I'm not certain as to the statistical calculation behind this, although I know it is not complex). Thanks.

    anyone? a little help here would be much appreciated.

      Our DESeq package uses an internal normalization, and our Preprint explains why normalizing explicitely is a bad idea anyway.

      Maybe that helps.

        Goby supports Upper Quartile normalization since version 1.5. See argument --normalization-methods at http://campagnelab.org/software/goby...tation-counts/

          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...
