  • % matching problem- RNA_Seq

    Hi
    I am a new SOLiD user, and completed our first RNA-Seq experiment. I have a question regd the secondary analysis report. For the secondary analysis we uploaded whole human genome as reference and the % matched summary report for our 2 samples were around 25%. But according to ABI the run is considered successful only if the % match is above 30%. Can anyone comment on what the problem might be of low % match.

    Thanks

    The mapping percentage is correlated with the mismatches setting, the sequence length and the mapping procedure. You can allow more mismatches and mapping full-length and 1/3 trim-length. maybe, you can got higher percentage. you know, SOLiD generally has more mismatches than Solexa.

      Exploring the Dynamics of the Tumor Microenvironment
      by seqadmin




      The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

      Exploring Human Diversity Through Large-Scale Omics
      by seqadmin


      In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
