Usage

Users should follow the following steps to compile DosageConvertor (if they downloaded the source files).

## EXTRACT M3VCFTOOLS AND COMPILE
 
wget ftp://share.sph.umich.edu/minimac3/DosageConvertor/DosageConvertor.v1.0.3.tar.gz
tar -xzvf DosageConvertor.v1.0.3.tar.gz
cd DosageConvertor/
make

The command options for DosageConvertor are explained below.

• "--vcfDose" is a mandatory parameter requiring the input VCF file.
• "--info" denotes the info file from the same imputation output. This parameter is NOT mandatory, but if NO info file is provided, the output MaCH info file will have some missing columns.
• "--prefix" denotes the output file prefix (default value: Converted.Dosage).
• "--type" denotes the output file format (available handles: mach (default) and plink).
• "--format" decides whether to import imputed values from dosage (DS) or genotype probabilities (GP) of the input VCF file (available handles: DS (default) and GP).
• "--buffer" denotes the number of markers to import at a time (valid only for MaCH format) (default value 10000).
• "--idDelimiter " denotes the delimiter to Split VCF Sample ID into FID and IID for PLINK format (default value _).

Usage: ./DosageConvertor  --vcfDose      TestDataImputedVCF.dose.vcf.gz
                          --info         TestDataImputedVCF.info
                          --prefix       OutputFilePrefix
                          --type         plink OR mach   // depending on output format
                          --format       DS or GP        // based on if you want to output
                                                         // dosage (DS) or genotype prob (GP)
                          --buffer       10000           // Number of Markers to import and
                                                         // print at a time (valid only for
                                                         // MaCH format)
                          --idDelimiter  _               // Delimiter to Split VCF Sample ID into
                                                         // FID and IID for PLINK format
