  • E-Values calculation (MEME)

    I'm trying to understand how MEME's E-values are calculated but can't find how could I reproduce a simple case with a few sequences, a PSPM and an E-value calculation.
    Tryied to find some source code of an implementation to try to debug it but was not able, please is somewhere an example of how to calculate MEME's
    E-values? Or an explanation of how they can be calculated?



    MEME reports an E-value for each motif it finds, which is an estimate of the number of (equally or more interesting) motifs one would expect to find by chance if the letters in the input sequences were shuffled. Motifs with small E-values (e.g., less than 0.001) are very unlikely to be random sequence artifacts.

    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...
