I have been trying to convert a VCF file downloaded from 1000genomes (VCF v4.1) using this tool. However, I keep getting the error message Fatal error: Exit code 1 ()
unable to find FASTA index entry for '22”

I am using the human hg19 reference genome. 

Our ultimate goal is to get phased data from 1000genomes in a FASTA format in order to calculate Tajima's D and Fay and Wu's H (measures to identify recent selective sweeps) on the sequences we are interested in.

I am new to this field, any help or advice in this regard would be greatly appreciated.

This looks like a reference genome mismatch issue.

Try using the 'hg_g1k_v37' genome instead of 'hg19'. That is the 1000 genomes human reference genome used by GATK.
