How to download the raw genotype file, convert it to VCF against a reference, lift it to GRCh38, impute, score, and know which conclusions the array can and cannot support.
A step-by-step guide to exporting raw genotype files from Ancestry, 23andMe, and MyHeritage, converting them to a reference-correct VCF, lifting to GRCh38, imputing, and understanding what an array file can and cannot tell you.
A breakdown of real 2026 prices for SNP arrays, exomes, and whole-genome sequencing, what each one measures, and the storage, compute, and interpretation costs that follow.
A technical answer to which genetic sites are worth uploading raw DNA to, what the array file contains, and how to run the same analyses yourself with plink, bcftools, and an imputation server.
DNA.Land stopped accepting uploads and shut down its reports. This guide shows how to take the same raw genotype file, convert it to VCF, impute it, annotate it, and decide which remaining upload sites are worth your data.
A practical pipeline for turning a tellmeGen raw data export into a build-verified VCF, running quality control, annotating it, and understanding what a genotyping array can and cannot tell you.
