    Tophat and SOLID -> zero kb .bed files

    Hello,

    I'm somewhat relatively new in the NGS data analysis though i've been reading and searching a lot for the last couple of months. I've recently got a new computer to do my own analysis and set up Tophat to run before i left work last night. I came into work to find this error message on terminal:

    Code:

    Seems like everything ran quite nicely but something failed and all the .bed files Tophat output are all 0kb. I tried searching google but couldn't find information related to this error. Any idea what this is?

      Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
      by SEQadmin2



      CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

      Despite this, “CRISPR helped turn genome editing from a specialized technique into

      Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
      by SEQadmin2


      Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

      The systematic characterization of the human proteome has
