    Difference between TopHat and Illumina-CASAVA

    We are analyzing illumina 75bp paired-end RNA-seq data. For mapping, what are the key differences between TopHat and Illumina's eland-CASAVA pipeline for RNA-seq data?

      I heard from a talk given by Illumina, casava is good for reads length <= 50.

        The Illumina pipeline will only look for known splice junctions, while TopHat can (at least in theory) find novel splice junctions.

          Hi kopi-o,

          Thanks for highlighting that difference.

          One other difference could be the no. of basepairs that the algorithm expects as the 'seed' in order to generate accurate alignments. For illumina-eland, I know it is 32bp, but not sure what seed length does TopHat expect.

            Hi kopi-o,

            Thanks for highlighting the difference on splice junction prediction between Illumina-Eland and TopHat.

              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

              How Immunogenomics Decodes Immunity’s Genetic Blueprint
              by SEQadmin2




              The immune system’s power comes from its genetic diversity, allowing myriad threats to be neutralized through first recognizing foreign antigens. That diversity is also what makes the immune system so difficult to study. Recent advances in sequencing technology and computational biology, however, are giving researchers new tools to understand immune responses and immune-related diseases in greater detail.

              This convergence of genetics, immunology, and computation...
