Code Block
cat input.vcf | grep AF1=1 > output.vcf

Is not practical, since we will lose vital VCF formatting and may not be able to use this file in the futre.

Code Block
cat input.vcf | grep -v AF1=0 > output.vcf

Code Block
sed -i '/AF1=0/ d' input.vcf

Is a better way of doing it inline and not requiring you to make another file.
