  • Can I use only one read from paired end reads for breseq analysis?

    Hello

    This might be a stupid question, but I have just discovered tool called Breseq for microbial variant and SV analysis. The problem is that I have only paired end reads while breseq uses only single end reads. In their FAQ section they wrote this :
    "Short answer: No.

    Your reads are mapped in single-end mode even if you are using paired-end or mate-paired data. For most microbial genomes, you don’t gain much sensitivity (in terms of the number of reference positions at which there are enough uniquely-mapped reads to call mutations) by doing paired read mapping. Furthermore, the split-read analysis approach that breseq uses to discover new sequence junctions is more precise (finding exact sequence breakpoints) and generally at least as sensitive as predicting structural variation by examining read pairs that are mapped with anomalous orientations and insert sizes.

    That said, there are definitely cases where this information can be useful, especially if one has data with large insert sizes (e.g. an Illumina mate paired library. So, we hope to include some of this functionality in the future. It just hasn’t been a very high priority."


    So my question is: Can I use just one of the reads from paired end reads or is that huge mistake? Also could I use both of the reads and then compare the results? I would really need answers to this questions.

    Thank you all in advance

    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...
