Introduction

m3vcftools is a tool (exactly similar to vcftools) but will be much faster and can be used for simple data query and basic summary like allele frequency, linkage-r2 calculation, etc. m3vcftools is ideal for mega reference panels like Haplotye Reference Consortium (HRC) with over 32,000 samples where m3vcftools is 70-90 times faster than vcftools (18 mins vs 28 hours) in calculating AF or LD summaries.

This wiki page gives users a full list of all the available options on m3vcftools .

The following table gives a brief description of all the parameters of m3vcftools . The software is in a very developmental mode and new options are going to be added regularly.

BASIC OPTIONS

INPUT FILE OPTIONS

Parameter	Description
--vcf or --in <input_filename>	VCF file or M3VCF file containing haplotype data for reference panel.
--passOnly	If ON, only variants will FILTER=PASS will be recorded from reference VCF file (does NOT work on M3VCF files yet).

INPUT FILE OPTIONS

Parameter	Description
--refHaps filename	VCF file or M3VCF file containing haplotype data for reference panel.
--passOnly	If ON, only variants will FILTER=PASS will be recorded from reference VCF file (does NOT work on M3VCF files yet).

Download

Minimac3 is available as an undocumented release version. The source files (and binary executable) are available for download in Source Files and commonly used reference panels in VCF and M3VCF formats are available for download in Reference Panels.
