I run Truvari for benchmarking of 2 vcf files truvari bench -b NA12878_S1.genome.vcf.gz -c b1.vcf.gz -o out. However, it gives the following error. First vcf file contains format, info, filter, contig and maxdepth headers, which is the vcf file I found on Internet. The second vcf file is output of a CNV calling software, which I converted from a bed file. It contains CHROM POS ID REF ALT QUAL FILTER INFO FORMAT SAMPLE columns and

##fileformat=VCFv4.2
##INFO=<ID=END,Number=1,Type=Integer>`

this above header. It gives the following error. I tried to find a solution but none works. Ant help can be appreciated.
