    Bowtie mapping error on color space data [Read is less than 4 charact?]

    Hi,

    I am using bowtie-0.12.7 to map genomic sequencing data of NCI-H209 cell line into human hg19 genome. The data is from this paper, and the color space .csfasta file is like that:

    # Title: S0020_20080602_1_2_3kb_4_
    >1_65_78_F3
    T0110200122031310012203232
    >1_65_110_F3
    T0300212221202330222130212
    >1_65_167_F3
    T0300010011322223223000011
    >1_65_188_F3
    T0100000032100011213033102
    >1_65_305_F3
    T0200012011300201011021211
    >1_65_560_F3
    T0110310212122001103001112
    >1_65_621_F3
    T3032102121011220311021112
    And the setting I use is as following:
    Code:
    bowtie-0.12.7/bowtie -f -p 8 -S -v 2 -m 1 -t hg19_c -C sample.csfasta sample.sam >> sample.log 2>&1
    After aligning ~4E8 reads, which is about 1/3 of total reads, bowtie report an error below:
    Error: Read (1_122_1720_F3) is less than 4 characters long
    terminate called after throwing an instance of 'int'
    Aborted
    But when I look into the csfasta file, that read is intact with 25bp
    >1_122_1605_F3
    T0000230330110303213113211
    >1_122_1666_F3
    T0030121112113303000031132
    >1_122_1720_F3
    T3021210332111212021021211

    >1_122_1796_F3
    T0201302031033230230331311
    >1_122_1832_F3
    T0023102022001211001001111
    Does anyone know what might be the reason for this problem and how to fix it?

    Thanks in advance!

    Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
    by SEQadmin2



    Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

    Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

    New Genomics Technologies Take Aim at Long-Standing Limits
    by SEQadmin2


    Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

    We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
