    Use perl to generate FASTA formatted file

    I'm trying to generate a FASTA file listing all the differential expression gene. I have output from cuffdiff: gene_exp.diff
    And I also have a reference genome. I was trying to use perl/extractGene.pl, but I cannot get output file...

    The job file:

    perl perl/extractGene.pl -d cuffdiff_JDMCA_merge/gene_exp.diff -g HC/ref_genome.fa

    But I don't have any output. Furthermore, both the error file and o file is 0, for example: the size of both perl.o1600164 and perl.e1600164 is 0.

    I'm not sure whether I expressed this problem clearly...

      You may have to do some filtering/pre-processing etc. if you are using this script:

      Details are there.

          Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
          by SEQadmin2



          Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

          Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating          ...

          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          ...
