Here is an example of how <code>arf</code> works:
Here are examples of how <code>arf</code> works:
#-c option directs the output to STDOUT
arf -a complexity 1000g.vcf -g genome.fa -l 30 -c
#-o option specifies an output file name
arf -a complexity 1000g.vcf -g genome.fa -l 30 -o paltum.vcf
#input VCF file can be gzipped
arf -a complexity 1000g.vcf.gz -g genome.fa -l 30 -o paltum.vcf
#multiple analyses/annotations at once is possible
arf -a complexity,f,hwe,exons 1000g.vcf.gz -g genome.fa -l 30 -o paltum.vcf -f refGene.txt.gz

You will also need a copy of human genome assembly fasta file: [http://www-personal.umich.edu/~atks/human.g1k.v37.fa.gz human.g1k.v37.fa]. Please gunzip it before usage. arf will generate a memory mapped file from the fasta file named human.g1k.v37-bs.umfa.
