How to convert vcf to impute2 format?

Question

[grishin]

Hi, i want to phase my data in vcf format using impute2's "-phase" option. So i tried to convert vcf file with plink:

plink --vcf data.vcf --recode oxford --out converted_data

But produced .map file does not conform to the required three-column format.
Is there any other way to convert vcf to impute2 format?

Can you clarify what the problem is? --recode oxford should produce a .gen file and a .sample file; this command shouldn't generate a .map file at all.
