This dataset contains concordance metrics between high and low-coverage VCF files of the IBS001 genome, belonging to an IBS (Iberian Populations in Spain) individual. This genome was sequenced at 40X coverage in both Illumina and MGI sequencing platforms, and then respectively downsampled to 1x coverage with samtools. Genotype likelihood calculations and calling was performed using bcftools, and imputation of the low-coverage genotypes was performed using GLIMPSE1.
