Default Adding a fake genotype column to a vcf file

Hello all!

I need to add a fake genotype column to my vcf files produced with lofreq in order to use them with vcf tools for specific analyses. Can anyone help me with this?

Here is an example of the vcf produced with lofreq

Code:
##fileformat=VCFv4.0
##fileDate=20171129
##source=lofreq call -f JW316_consensus.fa -o 316.vcf 316.sorted.bam 
##reference=JW316_consensus.fa
##INFO=<ID=DP,Number=1,Type=Integer,Description="Raw Depth">
##INFO=<ID=AF,Number=1,Type=Float,Description="Allele Frequency">
##INFO=<ID=SB,Number=1,Type=Integer,Description="Phred-scaled strand bias at this position">
##INFO=<ID=DP4,Number=4,Type=Integer,Description="Counts for ref-forward bases, ref-reverse, alt-forward and alt-reverse bases">
##INFO=<ID=INDEL,Number=0,Type=Flag,Description="Indicates that the variant is an INDEL.">
##INFO=<ID=CONSVAR,Number=0,Type=Flag,Description="Indicates that the variant is a consensus variant (as opposed to a low frequency variant).">
##INFO=<ID=HRUN,Number=1,Type=Integer,Description="Homopolymer length to the right of report indel position">
##FILTER=<ID=min_dp_10,Description="Minimum Coverage 10">
##FILTER=<ID=sb_fdr,Description="Strand-Bias Multiple Testing Correction: fdr corr. pvalue > 0.001000">
##FILTER=<ID=min_snvqual_65,Description="Minimum SNV Quality (Phred) 65">
##FILTER=<ID=min_indelqual_20,Description="Minimum Indel Quality (Phred) 20">
