Visualize variants annotated with ANNOVAR

[Nilaksha]

Hey all,

I'm developing a pipeline for NGS data analysis. I'm pretty much ok with the steps up to variant calling (I'm using GATK for that) and then I use the already built VCF file to convert it to an ANNOVAR compatible file for annotation. My problem is that, how can I incorporate ANNOVAR annotated files (there are several files I have got using Gene based/Filter based and Region based annotation) along with the VCF file in analysis. Can I add ANNOVAR annotated files as separate tracks along with VCF in visualisation programs like IGV?

Yes, you can. IGV can read a lots of data formats.

Yes, you can. IGV can read a lots of data formats.

I tried importing csv file obtained by table_annovar.pl script of ANNOVAR to IGV but had no luck. Is there any particular method that worked for you ?

I'd like to know this too. I've tried opening file.exonic_variant_function and file.variant_function, and neither are visualized by IGV. The best thing I can think of is to add the appropriate headers to the Annovar output to make it look like a vcf. I guess some fields will have to be added as well.

EDIT: I just looked at the Annovar output again and it looks like it's going to need a lot more work than simply adding a header and some fields. But I think it might still be doable. I'll post a solution if I come up with one.

I have worked with BED files, but IGV can read custom files:

Hey thanks a lot,

I guess I can work it out now/
