    Errors encountered while running Metasim

    Hi,

    I am using Metasim to simulate 454 reads. This is the 454 error model setting.
    Preset Name: 454
    Number Of Reads / Mate Pairs=5000
    Error Model=454

    454 Error Model Configuration=
    Number Of Cycles: 133 (~339 Base Pairs)
    Mate Pair Probability: 0.0
    Mate Pair Read Length: 20
    Remove Mate Pair Linker from Output: false
    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: 400.0
    2nd parameter: 20.0

    Combine All Files=false
    Uniform Sequence Weights=false
    Number Of Threads=1
    Write FastA=true
    Compress Output Files=true
    The Taxon profile is
    ### MetaSim taxon profile
    # 100 name "07-54825"
    100 taxid 1
    I run into this error (this is from the Simulator log file)

    java.lang.Exception: sequence file not found
    !!! FAILED !!!
    Please advise if I have missed anything in the settings or why this error possibly occurs.

    Thank you.

    Hi sandhya!

    Could you fix the error exception raise from MetaSim?
    It's happening to me now, after using MetaSim almost a year.

    Thank you so much

      Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
      by SEQadmin2



      Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

      Cancer Drug Resistance: The Lingering Barrier to Rising Survival
      by SEQadmin2



      Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

      There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

      Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing
      by GATTACAT
      Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
