Arf

arf is a genetic analysis program for sequencing data.

Basic Usage Example

 arf [options] <vcf-file>

Here is an example of how arf works:

  arf -s 1000g.vcf got2d.vcf -g hg18.fa  -w 10 -d

Command Line Options

   vcf-file     VCF file (can be gzipped or bgzipped)
   g              genome-file (Memory Mapped Sequence file) 
                  (note that if genome.fa is specified, the actual file looked for is genome-bs.umfa)
   s              statistical analysis
   a              annotation

Here is an example of how arf works:

   #computes HWE and F statistics from genotype likelihoods
   arf -s hwe,f  1kg.vcf

Output

   user@host:~$ vmatch gatk.vcf samtools.vcf -w 10 -d  
   

Description

   Outputs 2 files
     match.txt : gives the matched pairs
                 1)id1
                 2)id2
                 3)match type
                 4)extended no of bases
                 5)normalized
     match.log : Details of the extension and normalization process for all compared pairs
   vmatch matches the variants in 2 VCF files by choosing the best match for every
   possible variant pair.  The percentage of matches is given at 3 levels for each
   variant total of both VCF files.

Download

For arf 0.557215, we provide binaries for linux machines.

You will also need a copy of the memory mapped file: human.g1k.v37-bs.umfa. Please gunzip it before usage. Note that to use it, please refer to the file as human.g1k.v37.fa, it will be automatically renamed as human.g1k.v37-bs.umfa by arf.
