  • Multiple gene entries in cuffdiff output

    Hi, I am using the newest version of cufflinks. My gene_exp.diff output has multiple entries for the same gene.
    Any advice on how to interpret this?
    thanks, my output is below:

    Hi, I just wanted to update my previous post. I previously ran cufflinks in the following way, in order to find known and novel transcripts:
    I ran tophat without a reference, ran cufflinks without a reference on each bam file, ran cuffcompare with the ensemble ref and my output gtfs, and then ran cuffdiff on the combined gtf and bam files.
    Since I am mostly interested in known transcripts, I now reran tophat with the ensembl gtf and ran cuffdiff on that output with the ensembl gtf and the bam files.
    I now end up with only one value per gene, so I will use these much clearer results for now.

      Current Approaches to Protein Sequencing
      by seqadmin


      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
