  • Mosaik Aligner problem with SOLiD sequences

    Hi all,
    I have installed Mosaik 1.0 on two desktops to map SOLiD colorspace reads. On one desktop, the Aligner never quite worked: it would always choke on some input read or other with a message like:

    "ERROR: Unknown combination found when converting to basespace: [T] & [-]"

    I traced the first offending read in one of the input datasets, and there was nothing special about it.

    On the other desktop, Mosaik Aligner has been working fine, with only a recent issue similar to the Error described above: I tried to use the option where the reference genome has IUPAC ambiguity letters that allow more matches to them (e.g. an R in the reference could match to both an A or G in the read without a penalty).

    But the runs don't seem to work, the aligning process returns immediately errors like "Unknown combination found when converting to basespace: [Y] & [G]" (like I described above, always happes with my other installation).

    Anyone seen this issue? Ideas how to resolve it?

    Thanks

    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...
