  • CoCAS, with Agilent micro arrays

    Hi,

    I'm using CoCAS for my chip-on-chip analysis and I have an insolvent problem.

    Here is a link to download CoCAS :


    During analysis, it seems that CoCAS can not read the column "rMeanSignal" of my raw data, but this column is present on my file (i checked it with "cut -f 34 file.txt...") :

    ----------------------------------------------------
    Start Analysis...

    Reading Files...

    Read E:/result.TXT
    Arrays of slide 1 have been read. (no Dye-swap)

    Intra-Arrays Normalization Start...

    Slide 1

    computing p valuesErreur dans var(Xlow[which(Xlow < 0)]) : 'x' est vide
    De plus : Warning message:
    In read.maimages(noSwap, source = "generic", columns = list(R = "rMeanSignal", :
    non-standard columns specified


    -----------------------------------------


    Is somebody have already the same problem ? Thank you a lot for your help !!!

    Hi,

    I'm trying to install the linux version. I installed the R libraries, and when I launch the following command :

    java -jar COCAS_v2.4.jar

    I've got this error :

      Hello !

      I just solved my first problem :

      the "SystematicName" column must respect the syntax :"chrX:9numbers:9numbers".

      Have fun.

        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...
