  • Inquiry regarding input file for genome size estimation by Jellyfish

    Hi,

    Do anybody mind to share that what is the "best" or "suitable" input file for genome size estimation program such as Jellyfish?

    I still confuse should I used original raw sequencing read, pair-end data after preprocessing analysis (trim adaptor, remove low quality read, remove duplicate read, etc), or pair-end + single-end data after preprocessing analysis (trim adaptor, remove low quality read, remove duplicate read, etc)?

    I have try the above 3 different data as an input file for Jellyfish by using 17-mer.
    My data set is novel isolated bacteria.
    Thus I not too sure what is the exact genome size.

    The peak of 17-mer frequency (M) in reads is correlated with the real sequencing depth (N), read length (L), and kmer length (K), their relations can be expressed in a experienced formula: M = N * (L – K + 1) / L.

    All the above 3 different data set gives me different peak of 17-mer frequency.
    Thus it effect the calculation of genome size too.

    Thanks for any advice.

    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...
