    Extracting REF and ALT from VCF

    This may be a simple question.

    I am trying to extract CHR, POS, REF and ALT and other info from a VCF file to a txt file using vcftools. Can somebody point me how to get REF and ALT? I don't get this information but everything else.

    Thanks
    -K.

    I think vcf-to-tab does exactly that:
    vcf-to-tab < file.vcf

      Thank you, id0. It works and I get the genotypes. But I don't get other information from the FORMAT fields. I know I can use --extract-FORMAT-info separately and 'paste' these two lists, but I would be more comfortable if I can get the genotypes as well as the format fields information at the same time. Anyway, I thank you for the solution.

        Also, I will be just happy with the ALT entries instead of actual variants. Is it possible to get that?

        Thanks

          vcf's are naturally text files. If yours isn't, it's just compressed, so uncompress it.

            Thank you swbarnes2. I found VariantsToTable in GATK does exactly what I wanted.

              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.
