How to extract the allele dosage of .vcf.gz after TOPMed imputation?

Question

[Zulema]

Hello!

After TOPMed imputation I have from each chromosome thwo types of files:

• .vcf.gz
  • .info.gz

In the vcf.gz file I have the letter of the allele but, I need the allele dosage. How can I do this and get a vcf.gz file back?

Thanks in advance!
