  • MetaSim: why paired end reverse read is much shorter than forward read??

    Hi everyone! I'm new here...

    I simulated a library paired end 20 kb for 454 technology using MetaSim... but always the reverse read is so much shorter than forward read (forward average: 300 pb and reverse average: 50 pb)

    Somebody have any idea why???

    I checked the preset of the program and it looks right... so, I don't get it!

    Preset Name: 454
    Number Of Reads / Mate Pairs=100000
    Error Model=454

    454 Error Model Configuration=
    Number Of Cycles: 137 (~349 Base Pairs)
    Mate Pair Probability: 0.99
    Mate Pair Read Length: 350
    Remove Mate Pair Linker from Output: true
    Lognormal Distribution Mean: 0.23
    Lognormal Distribution Std. Deviation: 0.15
    Proportionality Constant for Std. Deviation: 0.15
    Scale Std. Deviation with Square Root of Mean: true
    Generate Signal Trace: false

    454 Error Model DNA Clone Parameters=
    Distribution: Normal
    Mean: 20000.0
    2nd parameter: 3000.0

    Combine All Files=false
    Uniform Sequence Weights=false
    Number Of Threads=4
    Write FastA=true
    Compress Output Files=false

    regards!!

    Non-Coding RNA Research and Technologies
    by seqadmin




    Non-coding RNAs (ncRNAs) do not code for proteins but play important roles in numerous cellular processes including gene silencing, developmental pathways, and more. There are numerous types including microRNA (miRNA), long ncRNA (lncRNA), circular RNA (circRNA), and more. In this article, we discuss innovative ncRNA research and explore recent technological advancements that improve the study of ncRNAs.

    Recent Developments in Metagenomics
    by seqadmin





    Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...
