    TopHat juncs file

    Hi,
    How to supply tophat with a list of raw junctions?
    Actually I have a set of splice junction set generated using refFlat and Solexa pipeline's splice_sites.pl. How do I convert it to raw-juncs file.

    How to generate GFF3 files for human as well as mouse?

    building a GFF3 file isn't a very straightforward process. for me it involved doing a bit of work at the command line including installing some Python libraries and downloading code from a CVS repository. you might want to just wait until Tophat supports GTF files which I understand is coming soon. GTF files can be downloaded straight from the UCSC Genome Bioinformatics Table Browser.

      Hi,
      This post is almost a year old. I am caught in the same situation and was wondering if someone has already written a script to convert refFlat to GFF3 format that I can use here.

          Convert UCSC Genome Browser-format gene files into GFF3 version files.
          Only the gene IDs and their locations come through. You have to get
          the comments and aliases some other way.

            It seems that the latest version of TopHat (1.1) allows you to use GTF files, which are more easily obtained. There is at least one other post I've seen detailing how to do that.

              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.

              Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
              by SEQadmin2



              Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.
