A whole genome array genotypes or copy-number-profiles preselected positions across all 24 chromosomes. Here is what the platforms resolve, the file formats you get, and how the data compares to 30x whole-genome sequencing.
A SNP microarray genotypes a fixed panel of several hundred thousand predefined positions and, from probe intensities, infers copy number and runs of homozygosity. Here is the data it produces, the tools to process it, and the variant classes it cannot see.
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 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.
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.
A FoundMyFitness report is a literature annotation layer on top of a consumer genotyping array. Here's how to audit the underlying file, rebuild the analysis yourself, and understand where array data runs out.
