    how to proceed with ChIP seq analysis

    Hi,

    I am new to ChIP seq analysis and would like to understand a few things. I want to analyze histone modification through SICER and already have the 36 base pair result aligned to the human genome.
    Since the genomic co-ordinates always overlap e.g.,
    chr1 0 36 ATCGCGCGAACTCGCGCGCGCTCGTCGTCAA 1000 +
    chr1 36 52 ATAGGGtCTCACATCTCGCGcTCGTCTCGCGAA 1000 +

    so on should I merge these intervals against the reference genome before running it against the resting cell ip through SICER to determine enrichment or run the intervals just like the way they are....

    kindly guide me....

    warm regards,
    Amit

    I'm not really sure what you are getting at. Work flow goes as:
    1) Align reads to reference genome (perhaps this was done for you). You should have two files, your input and ChIPed sample.
    2) Convert file (ELAND, SAM, BAM or whatever you have) to a BED file.
    3) Run SICER as described in readme.txt

    On a side note, I'll be glad to instruct you in person in you fly me down to Mauritious. Ha ha. Any open positions?

      dataset is kept here ....so I dont know the ChIped sample file that you are talking about

      NCBI's Gene Expression Omnibus (GEO) is a public archive and resource for gene expression data.


      and I am trying to learn ...I would appreciate if you could explain more it would be kind on your part....

      warm regards,

        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...

        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.
