    GTF file for maize?

    Hi,
    Is there a GTF file for maize? I know a GFF file exists but I'm using Cufflinks and need the GTF.
    Thanks,
    Ann

      Thanks for the link however the file only seems to contain entries for chromosome 9...

        Has anyone been able to locate a maize GTF file or create one from the GFF file from the Filtered Gene Set (http://ftp.maizesequence.org/current/filtered-set/)? Would be very useful.

        To convert a GFF into a GTF, it looks like it's just a matter of re-formatting, but I'm unclear as to how to do that.

          When we mentioned the 'chromosome 9' only problem to Ensembl they basically said "oops, will be corrected in the next release." Which was suppose to be today and, yes, I just checked, was today. See:

          ftp://ftp.ensemblgenomes.org/pub/release-9/plants/gtf/

          I haven't actually looked the maize GTF in detail yet -- that is now on my 'to do' list for the day -- but they do have entries for all 10 chromosomes.

            Oh, and in response to the comment

            Yeah, it looks like that. Harder to do than to say, though. Speaking from experience.

              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
