Using library htsjdk vcf files

[binfoUser]

I want to analyse VCF files that have annotations. I used programs like VEP to annotate the file and now I want to see and manipulate these annotations that are in the file.
I'm using a Java library htsjdk but until now I didn't find any method to manipulate one column (the annotations are added in the INFO column).

Can someone help?

there is currently no automatic method to parse the ouptut of VEP. you need to find the description of the INFO field for VEP from the https://samtools.github.io/htsjdk/ja...VCFHeader.html ( getInfoHeaderLine("CSQ") )

##INFO=<ID=CSQ,Number=.,Type=String,Description="Consequence type as predicted by VEP. Format: Allele|Gene|Feature|Feature_type|Consequence|cDNA_position|CDS_position|Protein_position|Amino_acids|Codons|Existing_variation|DISTANCE|STRAND|SYMBOL|SYMBOL_SOURCE|HGNC_ID">

and then, using something like "variantContext.getAttribute("CSQ")" , get the CSQ strings and split the result.

But the VCFHeader only access the file header and it gives me that line that you showed with id "CSQ". But now I want to extract the info added that is present in the data lines after the header.
I don't understand how to use the "variantContext.getAttribute("CSQ")" that you said. Does that give me that information?
