    Chip-seq analysis software

    Hi everyone,

    Is there people interested in ChIP-seq analysis ?
    I did not see too much threads on this topic...

    Well, I need to analyse ChIP-seq data from solid v3 system.
    I've used Sissrs and Macs for the peak detection but it seems that i do not find the same peaks in each analysis...

    Maybe this is due to the parameters i've used, but i look only for the moment
    for the 50 best peaks in term of Fold enrichment and i thought that it could be more or less the same peaks.
    Well i'm a bit disappointing, any help could be very appreciated.
    Here is the command lines i've ran for peak detection :
    Sissrs :
    perl sissrs.pl -i xxx.bed -o sissrs.bed -s 3080000000 -F 50 -L 100 -w 50 -b control.bed
    Macs :
    python macs -t xxx.bed --tsize=50 --format=BED --nomodel --name xxx --bw=100 --control=control.bed

    Anyway, i've developped a script running the SOLiDTM 3 System Application for ChIP Sequencing Analysis as describe on solidsoftwaretools.com and i want to test it with the dataset from the nature method paper on FOXA3 IP on solid (Chromatin immunoprecipitation sequencing (ChIP-Seq) on the SOLiD™ system).
    If someone know how to get the dataset i did not find it on the web.

    Thanks for any help,
    kevin.

    Nine Things a Sample Prep Scientist Thinks About Before Sequencing
    by SEQadmin2


    I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

    Here are nine questions we think about, in roughly the order they matter, before...

    From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
    by SEQadmin2


    Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


    The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
