  • Paralleling Control-FREEC chromosome by chromosome

    I'm wondering if anyone is an expert on Control-FREEC here.

    I've used this config file to run Control-FREEC on a tumor-normal WGS data:

    Code:
    [general]
    
    BedGraphOutput = TRUE
    breakPointThreshold = 0.8
    breakPointType=2
    chrLenFile = /PATH/TO/b37.len
    chrFiles = /PATH/TO/b37/contigs
    coefficientOfVariation = 0.05
    contaminationAdjustment = TRUE
    gemMappabilityFile = /PATH/TO/out100m2_hg19.gem
    minMappabilityPerWindow = 0.85
    forceGCcontentNormalization = 2
    ploidy = 2
    intercept = 0
    minCNAlength = 4
    outputDir = /PATH/TO/control_freec_experiment/setting_03c
    degree=3
    maxThreads = 2
    #readCountThreshold=10
    samtools = samtools
    sex = XX
    #telocentromeric=50000
    uniqueMatch=TRUE
    
    
    [sample]
    
    mateFile = /PATH/TO/wgs.tumor.pileup
    inputFormat = pileup
    mateOrientation = FR
    
    
    [control]
    
    mateFile = /PATH/TO/wgs.normal.pileup
    inputFormat = pileup
    mateOrientation = FR
    
    
    [BAF]
    
    SNPfile = /PATH/TO/hg19_snp131.SingleDiNucl.1based.txt
    minimalCoveragePerPosition = 5

    It worked well, but what I would really love to do, is to parallelize the process more, and process more of the data chromosome-by-chromosome if possible.

    Is there a good way to do that?
    For instance, is there a good way to generate the .cpn file chromosome by chromosome first, and then combine the .cpn files, then call CNV using those combined .cpn files?

    Thanks in advance for any help and suggestion!

    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...
