Parsing the TOPMed human chromosome 1 BCF with bcftools takes two days, so extracting the 137,977 samples one at a time or using thousands of parallel readers of the same file is impractical. Vcf-split solves this by generating thousands of single-sample outputs during a single sweep through the multi-sample input. END
