  • Abyss assembly with Ion Torrent?

    Anyone have any experience using Abyss to assembly Ion Torrent data? I am getting some pretty awful results I think.

    I have 100X MiSeq coverage (2x150) and 100X Ion Torrent data (avg read length a little under 200). I did a kmer parameter sweep on both. My best MiSeq assemblies are getting me right around 200contigs, which is pretty awesome. Unfortunately Ion Torrent is up around 10,000.

    I think it is likely I am doing something wrong, but not sure what.

    MiSeq command structure:
    abyss-pe -j 8 k=43 name=k43 in='MiSeq_100X_1.clipped.fastq.gz MiSeq_100X_2.clipped.fastq.gz' > k43.log 2>&1

    Ion structure:
    abyss-pe -j 8 k=43 name=k43 se='Ion_PGM3_100X.clipped.fastq.gz' > k43.log 2>&1


    I'm going to be trying out some other assemblers, but just wondering what the f is going on here...

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin


    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist on Modified Bases...

    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...
