    started a topic Kernel smoothing on tag counts

    Kernel smoothing on tag counts

    Hi all!
    I'm quite new with the analysis of ChIP-seq and RNA-seq data, and I just started a new project on the analysis of different kind of ENCODE data.
    Breifly, my problem is that I have to process multiple alignment files from different ChIP-seq assay (I meant different histone mod.) and convert them into normalized genome-wide signal coverage tracks, similar to the work performed in
    ENCODE-wiggler.
    Now I have to perform the analysis by my own with some modifications. I have for each ChIP-seq experiment wig files with coverage information (read counts) for each single position. I just wanted to use these files as input to generate density profile using kernel smoothing. Do you think is possibile to use the KernSmooth R package? I thought that this is exactly what I need but the function obviously compute density profile of data values in x, whilst I want to use it on values (tag counts) that are fixed along the chromosomic coordinate.
    Any suggestion? Is there maybe another package/function more suitable for this case? thanks a lot in advance.

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin




    The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

    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...
