  • tophat2 problem: No such file: left_kept_reads.m2g_um.candidates_and_unspl.bam

    I'm running into this problem while trying to get tophat2 to work. I'm running this on the test data that came with the software.

    I did get an accepted_hits.bam but it only contains the header.

    Check site tophat site for updated version of tophat2, same version number but different. Is the test set really only 100 reads? Might be insufficient?

        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...
