I am trying to add ancestral allele to 1000 Genomes Phase3 VCF files. I have used the "human_ancestor_GRCh37_e59.tar.bz2" files for ancestral allele input file. The steps I have used are:

cat human_ancestor_3.fa | sed 's,^>.*,>1,' | bgzip -c >

samtools faidx

Then using vcf-sort, sorted the chr3.vcf.gz file After that,

zcat sort.chr3.vcf.gz | fill-aa -a | bgzip-c>out.sort.chr3.vcf.gz

but it is giving the folllowing ERROR message:

[W::fai_fetch] Reference 3:60069-160069 not found in FASTA file, returning empty sequence Failed to fetch sequence in >3:60069-160069 The command "samtools faidx 3\:60069-160069" returned non-zero status 256.>3:60069-160069 at /usr/local/share/perl5/ line 56.
