− | Use the wrapper program "dose2vcf" to convert your doseage output to VCF format. Download the tool from [http://www.sph.umich.edu/csg/cfuchsb/dose2vcf_v0.4.tgz here].

− | Note that for longer chromosomes, the program is quite memory intensive. In this case, please convert dosages in shorter sections of the chromosome. For example, if the imputation was performed by sections, then convert these sections to vcf first, and then merge the vcf files together using vcftools [http://vcftools.sourceforge.net/docs.html#concat vcf-concat]: | + | Note that for longer chromosomes, the program is quite memory intensive.
