  • have i used CISA correctly

    Hi everyone

    Iv assembled a plasmid sequence and wanted to check whether I have done it correctly

    1. I first obtained read mapped contigs
    2. I secondly assembled contigs DE Novo using torrent assembler
    3. I then inputted these contigs onto CISA contig integrator, this resulted in a single contiguose sequence
    4. I then mapped my reads to the contiguose sequence and found an area of misaligned reads
    5. I split my contiguouse sequence at this point and ended up with 2 contigs
    6. I extended the two ends of the contigs by blasting my split contigs with my DeNovo contigs from another sequencing run I had
    7. I have now a circular genome that seems to have good read mapping and coverage. The read mapping at the ends of the contig is good.
    Was my use of CISA contig integrator correct? Im worried that if I add contigs from two methods the contiguouse sequence may have two copies of fragments.

    p.s. im using Iontorrant single end reads (400bp)

    Note: my main goal was to sequence a chromosomal sequence, i found out that i had a plasmid sequence when i blasted my contigs that did not map well onto contiguator

    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...
