    vcf filtering

    I have a multi sample vcf file. How can I filter only for overlapping snps within this one vcf file.
    As far as I understand, intersectBed and vcf-isec only work for different files.

    Thanks a lot for your help!

    Why not use those tools and intersect the file to itself?

      hm, but how can a target certain samples ? lets say I have a vcf with 10 samples. how to filter only for variants overlapping in samples 1 sample 3 and sample 7 ?

        Why not use vcf-subset to leave the samples in separate vcf's and then use vcf-isec?

          This is the solution I'm using, now. But with a growing sample number, this is really annoying. I thought there must be a more elegant one doing this in one step.

            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.

            Cancer Drug Resistance: The Lingering Barrier to Rising Survival
            by SEQadmin2



            Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

            There is no single reason why many patients don’t respond to treatment as expected. Cancer is...

            Reply to Nine Things a Sample Prep Scientist Thinks About Before Sequencing
            by GATTACAT
            Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
