    VEP variation cache

    Hi all

    When running VEP with ensembl annoation files I get errors of the form "Could not find variation cache for Chromosome..."

    I downloaded genome (ie. pao1, $name.fa) and annotation ($name.gff3) from ensembl ftp.
    Then created the cache files according to the VEP tutorial:


    sort -k1,1 -k4,4n $name.gff | bgzip > $name.gff.gz
    tabix -p gff $name.gff.gz
    ./cufflinks/gffread $name.gff -T -o $name.gtf
    perl gtf2vep.pl -i $name.gtf -f $name.fa -d 79 -s $name --dir variant_effect_predictor_version79/cache_files_
    and move the cache files to the correct location manually.

    Then mapped reads to the genome, ran freebayes (variants.vcf) and then vep with the following command:


    perl variant_effect_predictor.pl --everything --offline --custom $name.gff.gz,$name-genes,gff,overlap,0 --format vcf -i variants.vcf -o variants.txt --species $name --dir_cache $VEP_DATA

    I don't understand why I got this errors/warnings?

    Attached is the vep log output.

    Any help would be appreciated very much!

    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
