    convert snp chip data to VCF format

    Hi

    I have HumanOmni1-Quad_v1 SNP chip data, do anybody know how can i convert this data into VCF format which can be used as a reference for GATK inplace of dbSNP reference vcf file.
    The data looks like

    SNP Name,Sample ID,Allele1 - Top,Allele2 - Top,GC Score,Allele1 - Forward,Allele2 - Forward,Allele1 - Design,Allele2 - Design,Allele1 - AB,Allele2 - AB,Chr,Position,GT Score,Cluster Sep,SNP,ILMN Strand,Customer Strand,Top Genomic Sequence,Theta,R,X,Y,X Raw,Y Raw,B Allele Freq,Log R Ratio,CNV Value,CNV Confidence

      A bit late, sorry, but I believe this can be done by converting these files to PLINK format, and then using PLINK/SEQ (https://atgu.mgh.harvard.edu/plinkseq/output.shtml)

        Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
        by SEQadmin2



        CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

        Despite this, “CRISPR helped turn genome editing from a specialized technique into

        Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
        by SEQadmin2


        Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

        The systematic characterization of the human proteome has

        Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
        by SEQadmin2



        Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.
