How do I get a sub-section of a VCF file?

There are two ways to get a subset of a VCF file.

The first is to use the Data Slicer tool from our browser which is documented here. This tool gives you a web interface requesting the URL of any VCF file and the genomic location you wish to get a sub-slice for. This tool also works for BAM files. This tool also allows you to filter the file for particular individuals or populations if you also provide a panel file.

The second method is using tabix on the command line. e.g

tabix -h 2:39967768-39967768

Specifications for the VCF format, and a C++ and Perl tool set for VCF files can be found at vcftools on sourceforge

Please note that all our VCF files using straight intergers and X/Y for their chromosome names in the Ensembl style rather than using chr1 in the UCSC style. If you request a subsection of a vcf file using a chromosome name in the style chrN as shown below it will not work.

tabix -h chr2:39967768-39967768
