Inside the Variation toolkit: annotating a VCF with the data of NCBI biosystems mapped to BED.

Let's annotate a VCF file with the data from the NCBI biosystem.

First the 'NCBI biosystem' data are mapped to a BED file using the following script. It joins "ncbi;biosystem2gene", "ncbi:biosystem-label" and "biomart-ensembl:gene"


It produces a tabix-inded BED mapping the data of 'NCBI biosystem':

$ gunzip -c ncbibiosystem.bed.gz | head

I wrote a tool named VCFBed: it takes as input a VCF and annotate it with the data of a tabix-ed BED. This tool is available on github at https://github.com/lindenb/jvarkit#vcfbed. Let's annotate a remote VCF with ncbibiosystem.bed.gz :

java -jar dist/vcfbed.jar \
   TABIXFILE=~/ncbibiosystem.bed.gz \
   TAG=NCBIBIOSYS \
   FMT='($4|$5|$6|$7)'|\
grep -E '(^#CHR|NCBI)'

##INFO=<ID=NCBIBIOSYS,Number=.,Type=String,Description="metadata added from /home/lindenb/ncbibiosystem.bed.gz . Format was ($4|$5|$6|$7)">
