A filtered VCF file has been successful imputed using beagle 4.1 as follows:

java -Xmx24g -jar /programs/beagle41/beagle41.jar gt=/workdir/moshood/snps/snp_filtered.vcf.gz.recode.vcf nthreads=8 niterations=0  out=imputed_file

The output file named impute_file is phased and imputed. Could anyone guide me on appropriate software to use for converting the imputed file to dosage VCF format so that I could use it for further analysis? I would need the script as well. Thanks
