  • Annovar and variants with a MAF = 1 in fileterd file

    Hi,

    I'm a new user of annovar.
    When I filter with 1000 genomes database using the following command:
    perl annotate_variation.pl -filter -dbtype 1000g2014oct_eur -buildver hg19 my.vcf humandb/ -maf 0.01.
    In the filteted file I have the variants with a MAF lower than 0.01, but also the variants with a MAF equal to 1.
    Why the variants with a MAF of 1 appear here (in filtered file).
    For me it not make sense because I' m looking for “mutations”. Perhaps the answer is obvious but I don't see it.


    PD: I have searched previous post about annovar and I haven't found the answer, perhaps I have missed some of them.

    Investigating the Gut Microbiome Through Diet and Spatial Biology
    by seqadmin




    The human gut contains trillions of microorganisms that impact digestion, immune functions, and overall health1. Despite major breakthroughs, we’re only beginning to understand the full extent of the microbiome’s influence on health and disease. Advances in next-generation sequencing and spatial biology have opened new windows into this complex environment, yet many questions remain. This article highlights two recent studies exploring how diet influences microbial...

    Quality Control Essentials for Next-Generation Sequencing Workflows
    by seqadmin




    Like all molecular biology applications, next-generation sequencing (NGS) workflows require diligent quality control (QC) measures to ensure accurate and reproducible results. Proper QC begins at nucleic acid extraction and continues all the way through to data analysis. This article outlines the key QC steps in an NGS workflow, along with the commonly used tools and techniques.

    Nucleic Acid Quality Control
    Preparing for NGS starts with isolating the...
