    EnsEMBL variant effect predictor standalone error

    Hi all,

    I have extracted variation from bam files using samtools, now i want to annotate it using variant effect predictor perl script of EnsEMBL,

    [orf@localhost snp_effect_predictor]$ perl variant_effect_predictor.pl -i ../samtools-0.1.12a/samfiles/q20/vcf/GKUNU9Q04_chr1_q20_sort.vcf -format vcf -o chr1_.txt -w -b 2000

    it did well but applying for next time for another vcf file, i get error

    [orf@localhost snp_effect_predictor]$ perl variant_effect_predictor.pl -i ../samtools-0.1.12a/samfiles/q20/vcf/GKUNU9Q04_chr2_q20_sort.vcf -format vcf -o chr2_.txt -w -b 2000

    -------------------- EXCEPTION --------------------
    MSG: Start must be less than or equal to end+1
    STACK Bio::EnsEMBL::Feature::new /home/orf/EnsEMBL/src/ensembl/modules/Bio/EnsEMBL/Feature.pm:139
    STACK Bio::EnsEMBL::Variation::VariationFeature::new /home/orf/EnsEMBL/src/ensembl-variation/modules/Bio/EnsEMBL/Variation/VariationFeature.pm:177
    STACK toplevel variant_effect_predictor.pl:304
    Ensembl API version = 61
    ---------------------------------------------------

    It says there's may be a problem in vcf file but it worked well for GKUNU9Q04_chr1_q20_sort.vcf. I have used same commands for making vcf file for all chromosomes FYI.
    Am i doing anything wrong?

    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
