    GATK LiftOverVariants input vcf

    Hi,
    I am trying to convert a vcf file of b36 build to hg19.
    First few line of my vcf file:

    ##fileformat=VCFv4.0
    ##INFO=<ID=Database,Number=1,Type=String,Description="Database identifier">
    ##INFO=<ID=Dbxref,Number=.,Type=String,Description="Database reference">
    ##INFO=<ID=dbID,Number=1,Type=String,Description="Database identifier">
    ##INFO=<ID=ID,Number=.,Type=String,Description="Chromosome or contig">
    ##INFO=<ID=Alias,Number=.,Type=String,Description="Mostly novel variant">
    ##INFO=<ID=Variant_seq,Number=.,Type=String,Description="Alternate Allele">
    ##INFO=<ID=Genotype,Number=.,Type=String,Description="Homozyguous or Heterozyguous">
    ##INFO=<ID=Variant_reads,Number=.,Type=Integer,Description="Number of reads where variant present">
    ##INFO=<ID=Total_reads,Number=.,Type=Integer,Description="Total number of reads">
    ##INFO=<ID=Reference_seq,Number=1,Type=String,Description="Ancestral allele">

    chr1 555371 rs9283150 G A 22 .

    I have the vcf file validated using vcftools vcf-validator. But when I use the LiftOverVariants tool, it gives me the error:
    The providedVCF file is malformed at approximately line number 13: Trying to create a VariantContext with a ID key. Please use provided constructor argument ID.

    Please can someone tell me how to fix this?
    Thanks

    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
