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) andplink
)."--format"
decides whether to import imputed values from dosage (DS
) or genotype probabilities (GP
) of the input VCF file (available handles:DS
(default) andGP
)."--buffer"
denotes the number of markers to import at a time (valid only for MaCH format) (default value10000
)."--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
